It manages to achieve considerably higher performance to both the standard use Awk as well as GoAwk. The two reasons behind the significant speed boost offered by Pawk are the use of multi-threading programming, as well as the choice of Golang as the language of implementation. Since Pawk makes use of parallel programming, it is logical to be restricted only to operations that can be executed in parallel. However, we believe that Pawk can come handy in a plethora of cases, especially when dealing with multi-GB files. 7 | -------------------------------------------------------------------------------- /content/members/karakatsanis.md: -------------------------------------------------------------------------------- 1 | title: Konstantinos - Karakatsanis 2 | date: 20250228 3 | joined_date: 20250227 4 | category: members 5 | member_category: Researchers 6 | id: karakatsanis 7 | givenname: Konstantinos 8 | surname: Karakatsanis 9 | email: k_karakatsanis@outlook.com 10 | photo: karakatsanis.jpg 11 | 12 | Konstantinos 13 | holds an MS in Electrical and Computer Engineering 14 | from Georgia Tech 15 | and a BS in Management Science and Technology 16 | from the Athens University of Economics and Business. 17 | He was the instructor of the Intro to Computer Security class at Georgia Tech. 18 | 19 | His research interests include computer security, 20 | with a focus on firmware and software security, 21 | along with a longstanding interest in privacy. 22 | -------------------------------------------------------------------------------- /content/alumni/g_metaxo.md: -------------------------------------------------------------------------------- 1 | title: George - Metaxopoulos 2 | date: 20190621 3 | joined_date: 20190621 4 | category: alumni 5 | member_category: Researchers 6 | id: g_metaxo 7 | givenname: George 8 | surname: Metaxopoulos 9 | email: george.metaxopoulos@gmail.com 10 | github: gmetaxo 11 | linkedin: gmetaxo 12 | photo: g_metaxo.jpg 13 | 14 | **George Metaxopoulos** graduated with first-class honors from the Department of Management Science and Technology(AUEB) in 2018(specialization: Software Engineering and Data Science). 15 | 16 | Since then, he has worked for 1 year as a pre-sales technical member of IBM Greece's Cyber Security team, taking active part in various large-scale MSS projects. 17 | 18 | His main research interests involve Software Security and Privacy. 19 | -------------------------------------------------------------------------------- /content/seminars/2016-11-08.md: -------------------------------------------------------------------------------- 1 | title: Remove and Prevent: Dealing with Bugs in Software and Systems" 2 | presenter: Diomidis Spinellis 3 | date: 2016-11-09 4 | category: seminars 5 | 6 | Finding and fixing errors in computing systems is an important and 7 | difficult task.

Just as a radiation dosimeter measures dose uptake of external ionizing radiation, the epidemic dosimeter tracks potential exposure to viruses or bacteria associated with an epidemic. The dosimeter measures a person's exposure to an epidemic, such as COVID-19, based on exposure to contacts that have been tested positive. The epidemic dosimeter is designed to be widely accessible and to safeguard privacy. Specifically, it is designed to run on the $10 open-hardware Raspberry Pi Zero-W computer, with a minimal user interface, comprising LED indicators regarding operation and exposure risk and a physical interlock switch to allow the release of contact data. The software is based on the DP3T contact tracing "unlinkable" design and corresponding reference implementation code. 7 | -------------------------------------------------------------------------------- /content/seminars/2019-06-20.md: -------------------------------------------------------------------------------- 1 | title: Employing Different Program Analysis Methods to Study Bug Evolution 2 | presenter: Charalambos Mitropoulos 3 | date: 2019-06-20 4 | category: seminars 5 | 6 | The evolution of software bugs has been a well-studied topic in software engineering. 7 | We used three different program analysis tools to examine the different versions of two popular 8 | sets of programming tools (GNU Binary and Core utilities), 9 | and check if their bugs increase of decrease over time. 10 | Each tool is based on a different approach, 11 | namely: static analysis, symbolic execution, and fuzzing. 12 | In this way we can observe potential differences on 13 | the kinds of bugs that each tool detects 14 | and examine their effectiveness. 15 | To do so, we have performed a qualitative analysis on the results. 16 | Overall, our results indicate that we cannot say 17 | if bugs either decrease or increase over time 18 | and that the tools identify different bug types 19 | based on the method they follow. 20 | -------------------------------------------------------------------------------- /content/members/alampropoulos.md: -------------------------------------------------------------------------------- 1 | title: Lampropoulos-Andreas 2 | date: 20250710 3 | joined_date: 20250710 4 | category: members 5 | member_category: Associate Researchers 6 | id: alampropoulos 7 | givenname: Andreas 8 | surname: Lampropoulos 9 | github: antreasl 10 | email: a.lampropoulos.statistics@gmail.com 11 | linkedin: www.linkedin.com/in/andreas-lampropoulos 12 | photo: alampropoulos.jpg 13 | 14 | **Andreas Lampropoulos** is a PhD candidate at the Athens University of Economics and Business. 15 | His research focuses on intelligent data-centric approaches to dynamic resource allocation in distributed/cloud systems. 16 | He holds an MSc in Business Analytics from the Department of Management Science and Technology at the Athens University of Economics and Business, and a BSc in Statistics and Actuarial Science from the University of Piraeus. 17 | His academic interests span data engineering, distributed computing, applied mathematics, 18 | and the application of artificial intelligence to large-scale system optimization. 19 | -------------------------------------------------------------------------------- /content/seminars/2022-10-12.md: -------------------------------------------------------------------------------- 1 | title: Reality check on developers' perception! A case study of software testability and its effects 2 | presenter: Tushar Sharma 3 | date: 2022-10-12 4 | category: seminars 5 | 6 | Software testability is commonly defined as the degree to which the development of test cases can be facilitated by software design choices. Despite various studies on testability and its characteristics, the effects of testability on tests and overall software quality are unknown. In this presentation, I will discuss a catalog of four testability smells, and a survey targeted to gather software developers' perspectives on testability in general and our proposed testability smells in particular. I will also elaborate on a large-scale empirical study on 941 Java repositories containing approximately 11 million lines of code to investigate whether empirical data supports the perception of the developers on testability. Specifically, the study explores the relationship of testability with test quality, the number of tests, and reported bugs. 7 | -------------------------------------------------------------------------------- /content/seminars/2023-05-29.md: -------------------------------------------------------------------------------- 1 | title: The research and academic environment in the United States 2 | presenter: Georgios Liargkovas 3 | date: 2023-05-29 4 | category: seminars 5 | 6 | The research and academic environment in the United States 7 | is a topic of great interest to students and researchers worldwide. 8 | In this presentation, 9 | as an exchange student who recently returned from a program at Brown University, 10 | I will share my experience and provide (I think valuable) insights 11 | regarding the research environment, 12 | life in the US, 13 | and significant lessons I learned during this period. 14 | 15 | The presentation will begin with an introduction, 16 | covering the basic details of the program. 17 | Details about the US research environment, 18 | student life, 19 | challenges faced, 20 | and lessons learned will be then discussed. 21 | Finally, a brief reference will be made to the recently-accepted paper at HotOS '23 22 | "Executing Shell Scripts in the Wrong Order, Correctly", which will be presented in June. 23 | -------------------------------------------------------------------------------- /content/seminars/2017-01-23.md: -------------------------------------------------------------------------------- 1 | title: Does your configuration code smell? 2 | presenter: Tushar Sharma 3 | date: 2017-01-25 4 | category: seminars 5 | 6 | The wide adoption of configuration management and the increasing size 7 | and complexity of the associated code, prompt for assessing, 8 | maintaining, and improving the configuration code's quality.

It is aimed at developers, architects, and technology enthusiasts interested in exploring the historical and ongoing relevance of Unix's design principles. 10 | -------------------------------------------------------------------------------- /content/seminars/2016-10-11.md: -------------------------------------------------------------------------------- 1 | title: Augur: Incorporating Hidden Dependencies and Variable Granularity in Change Impact Analysis. 2 | presenter: Tushar Sharma 3 | date: 2016-10-12 4 | category: seminars 5 | 6 | Software change impact analysis (CIA) methods enable 7 | developers to understand potential impacts of a code change so that the 8 | change can be executed confidently without affecting reliability of the 9 | software. However, existing CIA approaches do not support CIA for all 10 | source code granularities. Additionally, they lack support for 11 | inter-granular change impact queries and hidden dependencies. In this 12 | presentation, I introduce Augur, an automated static code analysis-based 13 | CIA approach that addresses these shortcomings. Augur infers and 14 | maintains semantic and environment dependencies along with data and 15 | control dependencies between source code entities across granularities. 16 | Additionally, Augur uses Change Impact Query Language, a novel query 17 | language for impact analysis proposed in this paper, to support 18 | inter-granular CIA queries with batch querying feature. 19 | -------------------------------------------------------------------------------- /content/seminars/2021-05-20.md: -------------------------------------------------------------------------------- 1 | title: Maritime Analytics with Real-Time Big Ship Tracking Data 2 | presenter: Vasiliki Efstathiou 3 | date: 2021-05-20 4 | category: seminars 5 | 6 | Shipping has been the driving force of global trade for centuries. Today, it remains the major means of cargo transportation with almost 90% of the world’s goods estimated to be carried by sea. At the same time, shipping generates an enormous footprint of data that can unlock new possibilities for the maritime industry. 7 | 8 | MarineTraffic is currently the world’s leading platform offering ship tracking services and actionable maritime intelligence. Research at MarineTraffic is a paradigm of an applied research initiative, aiming to bring tangible outcomes to the market. This talk will present the lab’s efforts towards building systems for situational awareness at sea globally, demonstrating cases where the need for maritime intelligence is evident. The presentation will focus on ways of harnessing earth observation, ship tracking and behavioural data and will outline challenges and research opportunities in the journey to maritime digitalisation. 9 | -------------------------------------------------------------------------------- /content/seminars/2018-12-05.md: -------------------------------------------------------------------------------- 1 | title: Practices and Tools for Better Software Testing 2 | presenter: Davide Spadini 3 | date: 2018-12-05 4 | category: seminars 5 | 6 | Automated testing has become an essential process for improving the quality of software systems. In fact, testing can help to point out defects and to ensure that production code is robust under many usage conditions. However, writing and maintaining high-quality test code is challenging and frequently considered of secondary importance. Managers, as well as developers, do not treat test code as equally important as production code, and this behaviour could lead to poor test code quality, and in the future to defect-prone production code. The goal of my research is to bring awareness to developers on the effect of poor testing, as well as helping them in writing better test code. To this aim, I am working on 2 different perspectives: (1) studying best practices on software testing, identifying problems and challenges of current approaches, and (2) building new tools that better support the writing of test code, that tackle the issues we discovered with previous studies. 7 | -------------------------------------------------------------------------------- /content/seminars/2019-04-19.md: -------------------------------------------------------------------------------- 1 | title: Certified Robustness to Adversarial Examples with Differential Privacy 2 | presenter: Vaggelis Atlidakis 3 | date: 2019-04-19 4 | category: seminars 5 | 6 | Adversarial examples that fool machine learning models, particularly deep neural networks, have been a topic of intense research interest, with attacks and defenses being developed in a tight back-and-forth. Most past defenses are best effort and have been shown to be vulnerable to sophisticated attacks. Recently a set of certified defenses have been introduced, which provide guarantees of robustness to norm-bounded attacks, but they either do not scale to large datasets or are limited in the types of models they can support. This paper presents the first certified defense that both scales to large networks and datasets (such as Google’s Inception network for ImageNet) and applies broadly to arbitrary model types. Our defense, called PixelDP, is based on a novel connection between robustness against adversarial examples and differential privacy, a cryptographically-inspired formalism, that provides a rigorous, generic, and flexible foundation for defense. 7 | -------------------------------------------------------------------------------- /content/pages/contact.md: -------------------------------------------------------------------------------- 1 | Title: contact 2 | slug: contact 3 | 4 |

In this work, we explore how large language models (LLMs), which are nowadays introducing disruptive effects in many AI-based applications, can be used to build or improve sequential recommendation approaches. Specifically, we devise and evaluate three approaches to leverage the power of LLMs in different ways. Our results from experiments on two datasets show that initializing the state-of-the-art sequential recommendation model BERT4Rec with embeddings obtained from an LLM improves NDCG by 15-20% compared to the vanilla BERT4Rec model. Furthermore, we find that a simple approach that leverages LLM embeddings for producing recommendations, can provide competitive performance by highlighting semantically related items. We publicly share the code and data of our experiments to ensure reproducibility. 7 | -------------------------------------------------------------------------------- /content/seminars/2021-06-17.md: -------------------------------------------------------------------------------- 1 | title: Input Algebras 2 | presenter: Rahul Gopinath, Hamed Nemati, Andreas Zeller 3 | date: 2021-06-17 4 | category: seminars 5 | 6 | Grammar-based test generators are highly efficient in producing syntactically valid test inputs, and give their user precise control over which test inputs should be generated. Adapting a grammar or a test generator towards a particular testing goal can be tedious, though. We introduce the concept of a grammar transformer, specializing a grammar towards inclusion or exclusion of specific patterns: “The phone number must not start with 011 or +1”. To the best of our knowledge, ours is 7 | the first approach to allow for arbitrary Boolean combinations of patterns, giving testers unprecedented flexibility in creating targeted software tests. The resulting specialized grammars can be used with any grammar-based fuzzer for targeted test generation, but also as validators to check whether the given specialization is met or not, opening up additional usage scenarios. In our evaluation on real-world bugs, we show that specialized grammars are accurate both in producing and 8 | validating targeted inputs. 9 | -------------------------------------------------------------------------------- /content/alumni/echioteli.md: -------------------------------------------------------------------------------- 1 | title: Efstathia Chioteli 2 | givenname: Efstathia 3 | surname: Chioteli 4 | date: 20170818 5 | joined_date: 20170701 6 | category: alumni 7 | member_category: Researchers 8 | photo: stathoula.jpg 9 | id: echioteli 10 | email: hioteli.st@gmail.com 11 | github: stathoula 12 | linkedin: efstathia-chioteli 13 |

It is 7 | being used by the majority of websites and it is supported by all 8 | modern browsers. We present the rst large-scale study of client- side 9 | JavaScript code evolution. Speci cally, we have been collecting and 10 | storing JavaScript code from Alexa’s top 10000 websites on a daily 11 | basis (∼7.5 gb per day), for nine consecutive months. We have analyzed 12 | the resulting dataset to study how often developers deploy new scripts 13 | on the server-side. Our results indicate that the lifespan of scripts 14 | is quite short. That is, ve days for external scripts and one day for 15 | internal JavaScript code. In addition, we have examined how common 16 | JavaScript code reuse and especially the reliance to third-party 17 | libraries. Furthermore, we observed how software bugs evolve over 18 | time. To do so, we employed well-known static analysis tools to 19 | identify potential software bugs on the various scripts and then 20 | observed if they increase or decrease over time. 21 | -------------------------------------------------------------------------------- /content/seminars/2017-04-04.md: -------------------------------------------------------------------------------- 1 | title: Type Checking for Reliable APIs 2 | presenter: Maria Kechagia 3 | date: 2017-04-12 4 | category: seminars 5 | 6 | We propose to configure at compile time the checking associated with 7 | Application Programming Interfaces’ methods that can receive possibly 8 | malformed values (e.g. erroneous user inputs and problematic retrieved 9 | records from databases) and thus cause application execution failures. 10 | To achieve this, we design a type system for implementing a 11 | pluggable checker on the Java’s compiler and find at compile time 12 | insufficient checking bugs that can lead to application crashes 13 | due to malformed inputs. Our goal is to wrap methods when 14 | they receive external inputs so that the former generate checked 15 | instead of unchecked exceptions. We believe that our approach 16 | can improve Java developers’ productivity, by using exception 17 | handling only when it is required, and ensure client applications’ 18 | stability. We want to evaluate our checker by using it to verify 19 | the source code of Java projects from the Apache ecosystem. 20 | Also, we want to analyze stack traces to validate the identified 21 | failures by our checker. 22 | -------------------------------------------------------------------------------- /content/seminars/2017-06-12.md: -------------------------------------------------------------------------------- 1 | title: Mining Natural Language in Code Review Comments 2 | presenter: Vasiliki Efstathiou 3 | date: 2017-06-15 4 | category: seminars 5 | 6 | The growing availability of open software repositories has advanced 7 | research on mining software engineering data. Besides code-specic data, 8 | an interest towards developer communication data has emerged aiming to 9 | uncover features that impact on the software development lifecycle. Code 10 | reviews in particular, provide rich textual communicative information 11 | directly coupled with edits in source code. This talk will discuss 12 | possible unexplored directions towards analyzing natural language in 13 | code review comments, by adapting simple ideas from the community of 14 | linguistics. The proposed research aims to identify natural language 15 | patterns that imply higher level semantics, related to the underlying 16 | reasoning and intentions (such as necessity and probability), of the 17 | message conveyed in the comment. The ultimate goal in this context, is 18 | to uncover associations between the high-level semantics of comments and 19 | the revisions they suggest, and potential effects in comment usefulness. 20 | -------------------------------------------------------------------------------- /content/alumni/mloukeris.md: -------------------------------------------------------------------------------- 1 | title: Michael - Loukeris 2 | date: 20190205 3 | joined_date: 20190205 4 | category: alumni 5 | member_category: Researchers 6 | id: mloukeris 7 | givenname: Michael 8 | surname: Loukeris 9 | email: loukerismichalis@gmail.com 10 | github: milouk 11 | web_site: https://www.linkedin.com/in/mloukeris/ 12 | photo: mloukeris.jpg 13 | 14 | **Michael Loukeris** is an undergraduate student at the Athens University of Economics and Business (AUEB) in the Department of Management Science and Technology. 15 | 16 | Michael is a Technology and Entrepreneurship enthusiast.

It has many distributions for a plethora of devices. For many years, the only way to interact with the user was the command line. 7 | Shell commands are powerful, but their execution with options and arguments is difficult, because users cannot remember all of them. 8 | 9 | The goal of this work is to implement a graphical user interface which will guide the user on creating valid commands or shell scripts. The interface presents to the user the available options, arguments and their meaning. This information is extracted from each command's source code and documentation. 10 | 11 | The implementation can be split in two parts. The first one is the extraction of the required data for each command. The second one is the creation of a graphical user interface. 12 | The extraction tool is reliable for specific commands. However, there are some commands with special characteristics that cannot be extracted reliably. The graphical user interface works perfectly if it is fed with correct data. 13 | -------------------------------------------------------------------------------- /content/seminars/2018-05-23_a.md: -------------------------------------------------------------------------------- 1 | title: Code Review Comments: Language Matters 2 | presenter: Vasiliki Efstathiou 3 | date: 2018-05-23 4 | category: seminars 5 | 6 | Recent research provides evidence that effective communication in collaborative 7 | software development has significant impact on the software development lifecycle. 8 | Although related qualitative and quantitative studies point out textual 9 | characteristics of well-formed messages, the underlying semantics of the 10 | intertwined linguistic structures still remain largely misinterpreted or ignored. 11 | Especially, regarding quality of code reviews the importance of thorough feedback, 12 | and explicit rationale is often mentioned but rarely linked with related linguistic 13 | features. 14 | As a first step towards addressing this shortcoming, we propose grounding 15 | these studies on theories of linguistics. 16 | We particularly focus on linguistic structures of coherent speech and explain how 17 | they can be exploited in practice. 18 | We reflect on related approaches and examine through a preliminary study on four 19 | open source projects, possible links between existing findings and the directions 20 | we suggest for detecting textual features of useful code reviews. 21 | -------------------------------------------------------------------------------- /content/projects/iraklitos_dimitro.md: -------------------------------------------------------------------------------- 1 | title: Iraklitos II 2 | date: 20100901 3 | category: projects 4 | completed: 1 5 | id: p_iraklitos_dimitro 6 | shortname: Iraklitos II 7 | projtitle: Secure Software Development Technologies 8 | startdate: 20100901 9 | enddate: 20130901 10 | web_site: http://irakleitos.aueb.gr/index.php/erevnitikoergo/det/mitropoulos 11 | our_budget: 12 | total_budget: 45,000 € 13 | funding_agency: Ministry of Education 14 | funding_programme: Special Management Programme for Education and Lifelong Learning - Action 11.74.11.01 - Iraklitos II research fellowships at the Athens University of Economics and Business 15 | project_code: 4/15/6 16 | logo: stereo_espa.png 17 | scientific_coordinator: m_dds 18 | contact: m_dimitro 19 | project_manager: 20 | type: rtd 21 | international: no 22 | 23 | Code injection attacks are one of the most damaging class of attacks because: they can occur in different layers, like databases, native code, applications, libraries and others; and they span a wide range of security and privacy issues, like viewing sensitive information, destruction or modification of sensitive data, or even stopping the execution of the entire application.

This can be used to address known 8 | generalizability concerns, and, also, to perform research on open 9 | source business software development. Based on the premise that an 10 | enterprise's employees are likely to contribute to a project developed 11 | by their organization using the email account provided by it, we mine 12 | domain names associated with enterprises from open data sources as 13 | well as through white- and blacklisting, and use them through three 14 | heuristics to identify 17,264 enterprise GitHub projects. We provide 15 | these as a dataset detailing their provenance and properties. A manual 16 | evaluation of a dataset sample shows an identification accuracy of 89%. 17 | Through an exploratory data analysis we found that projects are staffed 18 | by a plurality of enterprise insiders, who appear to be pulling more 19 | than their weight, and that in a small percentage of relatively large 20 | projects development happens exclusively through enterprise insiders. 21 | -------------------------------------------------------------------------------- /content/seminars/2020-07-03-papachristoumarios.md: -------------------------------------------------------------------------------- 1 | title: Stochastic Opinion Dynamics for User Interest Prediction in Online Social Networks 2 | presenter: Marios Papachristou 3 | date: 2020-07-03 4 | category: seminars 5 | 6 | In this seminar, we are going to talk about how one can infer the interests (e.g. hobbies) 7 | of users in online social networks using information from highly influential users of the 8 | network. More specifically, we experimentally observe that the majority of the network users 9 | (>70%) is dominated by a sublinear fraction of highly-influential nodes (core nodes). 10 | This structural property of networks is also known as the "core-periphery" structure, 11 | a phenomenon long-studied in economics and sociology. 12 | 13 | Using the influencers' initial opinions as steady-state trend-setters, we develop a generative 14 | model through which we explain how the users' interests (opinions) evolve over time, 15 | where each peripheral user looks at her k-nearest neighbors. Our model has strong theoretical 16 | and experimental guarantees and is able to surpass node embedding methods and related opinion 17 | dynamics methods and is able to scale to networks with millions of nodes. 18 | 19 | Duration: 30-40min. 20 | 21 | Joint work with D.

Our core component is a program generator suitably crafted for producing programs that are likely to trigger typing compiler bugs. One of our main contributions is that our program generator gives rise to transformation-based compiler testing for finding typing bugs. We present two novel approaches (type erasure mutation and type overwriting mutation) that apply targeted transformations to an input program 7 | to reveal type inference and soundness compiler bugs respectively. Both approaches are guided by an intra-procedural type inference analysis used to capture type information flow. 8 | 9 | We implement our techniques as a tool, which we call Hephaestus. The extensibility of Hephaestus enables us to test the compilers of three popular JVM languages: Java, Kotlin, and Groovy. Within nine months of testing, we have found 156 bugs (137 confirmed and 85 fixed) with diverse manifestations and root causes in all the examined compilers. Most of the discovered bugs lie in the heart of many critical components related to static typing, such as type inference. 10 | -------------------------------------------------------------------------------- /content/seminars/2025-04-30.md: -------------------------------------------------------------------------------- 1 | title: Reconstructing Android Application I/O Behaviors from Kernel Traces 2 | date: 2025-04-30 3 | presenter: Nikos Alexopoulos 4 | category: seminars 5 | time: 18:00 6 | 7 | Android users face increasingly sophisticated threats, ranging from 8 | malware and state-sponsored surveillance, to supply chain attacks and a 9 | large attack surface, mostly consisting of proprietary components. 10 | Android’s semantic gap, i.e. the disconnect between application 11 | behaviors and kernel-level events (system calls), is a major limiting 12 | factor towards developing approaches capable of detecting threats in 13 | the wild. This talk will present recent research on overcoming this 14 | limitation, introducing SysDroid, a simple and lightweight approach to 15 | reconstruct Android behaviors from Linux kernel traces. 16 | 17 | SysDroid builds on two key insights: (a) I/O events can be captured in 18 | the kernel and attributed to applications by following IPC edges, and 19 | (b) a mapping between I/O events and interesting high-level behaviors 20 | can be established a priori by associating I/O events to high-level 21 | Android Framework API calls. The approach is effective in capturing 22 | application behaviors and can be used as the basis for further 23 | analysis. 24 | -------------------------------------------------------------------------------- /content/seminars/2023-10-04.md: -------------------------------------------------------------------------------- 1 | title: SCALE-BOSS: A framework for scalable time-series classification using symbolic representations 2 | presenter: Apostolos Glenis 3 | date: 2023-10-04 4 | category: seminars 5 | 6 | Time-Series Classification (TSC) is an important problem in many fields across sciences. Many algorithms for TSC use symbolic representation to combat noise. In this paper we propose a framework, namely SCALE-BOSS, to build TSC algorithms that exploit time-series models based on symbolic representations. While alternative symbolic representations can be incorporated, we have opted to use the Bag-Of-SFA (BOSS) approach, and thus SFA, as a state-of-the-art symbolic time series representation. We investigate the efficiency of several instantiations of this framework based on two main variations, where the TSC model is built either by a time-series classification or by a clustering algorithm. The objective is to advance the computational efficiency of TSC classification algorithms without sacrificing their accuracy. We evaluate the instantiations of the SCALE-BOSS framework on those datasets in the UCR time-series repository that include the largest training sets. Comparisons with state of the art methods on TSC show the balance between computational efficiency and accuracy on predictions achieved. 7 | -------------------------------------------------------------------------------- /content/alumni/agkortzis.md: -------------------------------------------------------------------------------- 1 | title: Antonios - Gkortzis 2 | date: 20151220 3 | joined_date: 20151220 4 | end_date: 20230401 5 | category: alumni 6 | member_category: Associate Researchers 7 | id: m_agkortzis 8 | givenname: Antonios 9 | surname: Gkortzis 10 | memb_title: Mr. 11 | email: antoniosgkortzis@aueb.gr 12 | photo: agkortzis_ssmall.jpg 13 | phd_title: Secure Systems on Cloud Computing Infrastructures 14 | phd_supervisor: m_dds 15 | phd_startdate: 20160104 16 | phd_completed: 0 17 | 18 | _Antonios Gkortzis_ has been a PhD Candidate at the SENECA (http://senecaproject.github.io/) project.

The Greek ICT-enabled consultation platform, Opengov, is used 8 | as a case study to measure consultation impact on voted law. Literature generally 9 | agrees that the goal of consultations is — among others — impact on developed 10 | policy, however there is not a universally accepted way of measuring this impact. 11 | This thesipos takes its own approach to defining impact as the similarity between 12 | draft legislation and voted legislation. Work from the public consultation field and 13 | the Natural Language Processing is presented. An extensive data collection and 14 | extraction process was necessary for this analysis which is also shown. Ordinary 15 | Least Squares (OLS) analysis was used to assert and quantify impact. Results show, 16 | among other explanatory variables, that the more contributions draft legislation gets, 17 | the more it changes on average. The thesis finishes with discussion of the results, 18 | the limitations of the selected approach and suggests ideas for improvement. 19 | -------------------------------------------------------------------------------- /content/members/mfg.md: -------------------------------------------------------------------------------- 1 | title: Marios - Fragkoulis 2 | date: 20091101 3 | joined_date: 20091101 4 | category: members 5 | member_category: Senior Researchers 6 | id: m_mfrag 7 | givenname: Marios 8 | surname: Fragkoulis 9 | memb_title: Dr. 10 | email: mfg@aueb.gr 11 | web_site: http://mariosfragkoulis.gr 12 | photo: m_mfg.jpg 13 | phd_title: Technologies for main memory data analysis 14 | phd_supervisor: m_dds 15 | phd_startdate: 20100901 16 | phd_enddate: 20170307 17 | phd_completed: 1 18 | 19 | _Marios Fragkoulis_ holds a PhD in main memory data analytics from the Department of Management Science and Technology of the Athens University of Economics and Business.

First, an investigation of data papers in the Mining Software Repositories conference confirms their significant value as research artifacts while identifying opportunities for improved documentation and broader topic coverage. Second, the practical impact of software engineering research is assessed through a patent analysis and author survey, demonstrating that researchers successfully equip practitioners with tools and methods, though adoption is often hindered by funding and cost-benefit challenges. Third, a comprehensive tertiary study analyzes machine learning applications in software engineering, revealing widespread adoption across tasks but significant gaps in empirical validation and industrial transfer. Finally, the work explores Large Language Models in code completion, analyzing code perplexity to understand model confidence across different programming languages. Together, these contributions offer a holistic view of how academic research translates into practice and how emerging technologies are shaping the future of software engineering. 8 | -------------------------------------------------------------------------------- /content/seminars/2021-01-15.md: -------------------------------------------------------------------------------- 1 | title: R-FCN: Object Detection via Region-based Fully Convolutional Networks 2 | date: 2021-01-15 3 | presenter: Zoe Kotti 4 | category: seminars 5 | 6 | We introduce the region-based convolutional neural networks (R-CNN) family of machine learning models, which are widely used in computer vision for object detection. Particularly, we focus on the R-FCN model, a region-based, fully convolutional network for accurate and efficient object detection. In contrast to previous region-based detectors such as Fast/Faster R-CNN, that apply a costly per-region subnetwork hundreds of times, R-FCN is fully convolutional with almost all computation shared on the entire image. To achieve this goal, position-sensitive score maps are proposed to address a dilemma between translation-invariance in image classification and translation-variance in object detection. This method can thus naturally adopt fully convolutional image classifier backbones, such as the latest Residual Networks (ResNets), for object detection. The authors of this work show competitive results on the PASCAL VOC datasets (e.g., 83.6% mAP on the 2007 set) with the 101-layer ResNet. Meanwhile, the result is achieved at a test-time speed of 170ms per image, 2.5-20x faster than the Faster R-CNN counterpart. Code is made publicly available at: https://github.com/daijifeng001/r-fcn. 7 | -------------------------------------------------------------------------------- /content/seminars/2025-11-24.md: -------------------------------------------------------------------------------- 1 | title: TGIF: The Evolution of Developer Commit Times 2 | presenter: Ioannis Karyotakis and Evangelos Talos 3 | date: 2025-11-24 4 | time: 18:15 5 | category: seminars 6 | 7 | Understanding the evolving patterns of developer coding activity within the programming industry can help promote both individual well-being and organizational productivity. We examine the evolution of commit activity among developers over the past decade through an analysis of commit data from 4\,549 GitHub repositories. Our findings show a subtle but consistent increase in the proportion of nighttime and weekend commits, particularly during early morning hours, indicating a shift toward more flexible and asynchronous work habits. In contrast, commit patterns across weekdays have remained stable, with no statistically significant differences between individual workdays from 2015 to 2024. These trends suggest a gradual departure from the conventional 9-to-5, Monday-to-Friday structure, with developers increasingly distributing their work across broader time frames. Our findings have practical implications for developers, who can use them to advocate for flexible work policies; for managers, who can better align schedules with real-world behaviors; and for researchers, who can further explore how temporal work patterns influence productivity and well-being. 8 | -------------------------------------------------------------------------------- /bin/seminar-add: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | # 3 | # Add a new seminar 4 | # 5 | # Copyright 2024 Diomidis Spinellis 6 | # 7 | # Licensed under the Apache License, Version 2.0 (the "License"); 8 | # you may not use this file except in compliance with the License. 9 | # You may obtain a copy of the License at 10 | # 11 | # http://www.apache.org/licenses/LICENSE-2.0 12 | # 13 | # Unless required by applicable law or agreed to in writing, software 14 | # distributed under the License is distributed on an "AS IS" BASIS, 15 | # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 16 | # See the License for the specific language governing permissions and 17 | # limitations under the License. 18 | # 19 | 20 | # Fail on command errors and unset variables 21 | set -eu 22 | 23 | # Display usage information and exit 24 | usage() 25 | { 26 | cat <&2 27 | Usage: $(basename $0) yyyy-mm-dd 28 | EOF 29 | exit 1 30 | } 31 | 32 | if [ $# != 1 ] || ! echo $1 | grep -qE '^[0-9]{4}-[0-9]{2}-[0-9]{2}$' ; then 33 | usage 34 | fi 35 | 36 | if [[ "${PWD##*/}" != "seminars" ]] ; then 37 | echo Command must run in the seminars directory 1>&2 38 | exit 1 39 | fi 40 | 41 | cat >$1.md <

RESTler analyzes the API specification of a cloud service and generates sequences of requests that automatically test the service through its API. RESTler generates test sequences by (1) inferring producer-consumer dependencies among request types declared in the specification (e.g., inferring that “a request B should be executed after request A” because B takes as an input a resource-id x produced by A) and by (2) analyzing dynamic feedback from responses observed during prior test executions in order to generate new tests (e.g., learning that “a request C after a request sequence A;B is refused by the service” and therefore avoiding this combination in the future). 7 | 8 | We present experimental results showing that these two techniques are necessary to thoroughly exercise a service under test while pruning the large search space of possible request sequences. We used RESTler to test GitLab, a large open-source self-hosted Git service, as well as several Microsoft Azure and Office365 cloud services. RESTler found 28 bugs in Gitlab and several bugs in each of the Azure and Office365 cloud services tested so far. These bugs have been confirmed and fixed by the service owners. 9 | -------------------------------------------------------------------------------- /content/seminars/2024-04-29.md: -------------------------------------------------------------------------------- 1 | title: Data Analytics with Blockly and Unix Tools 2 | presenter: Pantelis Kakavas and Vagelis Tsipis 3 | date: 2024-04-29 4 | time: 18:00 5 | category: seminars 6 | 7 | We introduce a new approach to integrating Unix command-line tools with 8 | visual programming, aiming to enhance accessibility and usability in data 9 | processing pipelines. Leveraging Blockly, a visual programming language, 10 | Unix commands are represented as graphical blocks, removing the need for 11 | advanced programming skills and making them more accessible to a broader 12 | audience. The creation of a visual programming environment enables users 13 | to construct data processing pipelines through drag-and-drop actions, 14 | facilitated by JSON definition files that create Unix command line 15 | tool abstractions linking visual blocks to Unix commands. The design 16 | is user friendly and deepens users' comprehension of Unix commands, 17 | improving accessibility for difficult data manipulation tasks. The 18 | project highlights the importance of visual programming in bridging 19 | the gap between complex command-line operations and user-friendly 20 | interfaces, thereby expanding the toolkit available for data scientists 21 | and researchers of various fields, while also offering new opportunities 22 | for interactive educational tools in command-line interface learning. 23 | -------------------------------------------------------------------------------- /content/projects/iraklitos_vlachos.md: -------------------------------------------------------------------------------- 1 | title: Iraklitos 2 | date: 20021108 3 | category: projects 4 | completed: 1 5 | id: p_iraklitos_vlachos 6 | shortname: Iraklitos 7 | projtitle: Security Applications for Peer-to-Peer Networks 8 | startdate: 20021108 9 | enddate: 20070530 10 | web_site: 11 | our_budget: 12 | total_budget: 33,009 13 | funding_agency: Ministry of Education 14 | funding_programme: Programme for Education and Initial Vocational Training II (EPEAEK II) - Action 2.2.3.b - Iraklitos research fellowships at the Athens University of Economics and Business 15 | project_code: 19 16 | logo: 17 | scientific_coordinator: m_dds 18 | contact: m_vlachos 19 | project_manager: 20 | type: rtd 21 | international: no 22 | 23 | During the last years several worm epidemics have emerged as major threats to critical digital infrastructures. 24 | To make large-scale networks more resilient against these kind of threats, we evaluate the usage of peer-to-peer architectures whereby each peer is responsible for 25 |

Understanding Security Vulnerabilities in SNARKs 2 | presenter: Stefanos Chaliasos, Imperial College London 3 | date: 2024-05-10 4 | time: 17:30 5 | category: seminars 6 | 7 | Zero-knowledge proofs (ZKPs) have evolved from being a theoretical concept providing privacy and verifiability to having practical, real-world implementations, with SNARKs (Succinct Non-Interactive Argument of Knowledge) emerging as one of the most significant innovations. Prior work has mainly focused on designing more efficient SNARK systems and providing security proofs for them. Many think of SNARKs as "just math," implying that what is proven to be correct and secure is correct in practice. In contrast, this paper focuses on assessing end-to-end security properties of real-life SNARK implementations. We start by building foundations with a system model and by establishing threat models and defining adversarial roles for systems that use SNARKs. Our study encompasses an extensive analysis of 141 actual vulnerabilities in SNARK implementations, providing a detailed taxonomy to aid developers and security researchers in understanding the security threats in systems employing SNARKs. Finally, we evaluate existing defense mechanisms and offer recommendations for enhancing the security of SNARK-based systems, paving the way for more robust and reliable implementations in the future. 8 | -------------------------------------------------------------------------------- /content/seminars/2018-12-17.md: -------------------------------------------------------------------------------- 1 | title: High-availability in scale-out stream processing 2 | presenter: Marios Fragkoulis 3 | date: 2018-12-17 4 | category: seminars 5 | 6 | Data stream processing 7 | offers low latency processing of bounded and unbounded data sets with strict semantics 8 | over the time dimension of data and consistent fault-tolerant operation. 9 | The applicability of data stream processing and the maturity of current 10 | stream processing systems (SPS) has produced 11 | numerous and large scale deployments around the world for commercial and other 12 | important use cases, such as fraud detection, risk analysis, and disaster prediction. 13 | 14 | When processing unbounded data for commercial or critical purposes 15 | the capability to recover from failures quickly, if not transparently, is 16 | important. 17 | In this work in progress we study three different recovery configurations: 18 | - restart recovery, which restarts a stream processing job in case of an operator failure from the latest checkpointed state 19 | - standby task recovery, which substitutes a failed operator with a standby instance 20 | - process pair, which runs two coordinated instances of a stream processing job in order to switch from one to the other in case of failure. 21 | Through empirical experiments we plan to 22 | map the tradeoffs between availability and resource utilization between 23 | the recovery configurations. 24 | -------------------------------------------------------------------------------- /content/seminars/2024-06-03.md: -------------------------------------------------------------------------------- 1 | title: AppStack: An Agile Platform for Running Digital Public Services 2 | presenter: Dimitris Mitropoulos, BALab 3 | date: 2024-06-03 4 | time: 18:00 5 | category: seminars 6 | 7 | From 2019 and onwards, the Greek National Infrastructures for Research 8 | and Technology (GRNET) is responsible for the development, operation and 9 | maintenance of several governmental services, thus playing an important 10 | role in Greece's digital transformation. To address the different 11 | challenges related to this role, GRNET teams developed AppStack, 12 | a cloud-native platform for running gov.gr horizontal services such 13 | as the gov.gr portal, the electronic issuance of documents signed by 14 | the Greek state, and gov wallet among others. AppStack comes with an 15 | enabling environment for integrating open-source software components. By 16 | taking advantage of this feature, DevOps can incorporate suitable tools 17 | to tackle scalability and security issues. Currently, AppStack hosts 18 | workloads that serve more than 8 million Greek citizens, are able to 19 | handle more than 20K requests per second, and can generate hundreds of 20 | digital documents signed by the Greek state per second. In this talk we 21 | will present AppStack and highlight the significance of its different 22 | components through a number of use cases.

With the proposed research we will aim to synthesize empirical findings coming of the analysis of the evolution and the behavior of software bugs that lead to code injection attacks, with existing pieces of theoretical work into an approach that covers all types of code injection attacks. Then, we will try to apply out approach to tame such attacks in different problem domains (web, mobile, etc.). For every application of our method, we will provide corresponding prototypes, deploy them in real world conditions and test them in terms of accuracy, operation cost and maintenance cost. 23 | -------------------------------------------------------------------------------- /content/alumni/chrikon.md: -------------------------------------------------------------------------------- 1 | title: Christos - Oikonomou 2 | date: 20140115 3 | joined_date: 20140115 4 | end_date: 20170530 5 | category: alumni 6 | member_category: Researchers 7 | id: m_chrikon 8 | givenname: Christos 9 | surname: Oikonomou 10 | memb_title: 11 | email: chrikon@dmst.aueb.gr 12 | web_site: http://altebaran.dmst.aueb.gr/FS/Students2012/chrikon/inetpub/detfolio/ 13 | mobile_phone: +30 6947359872 14 | fax: 15 | office_address: Athens University of Economics and Business Main Building, Derigny ct, 3rd fl 16 | postal_address: Patision 76, GR-104 34 Athens, Greece 17 | photo: chrikon.jpg 18 | 19 | _Christos Oikonomou_ is a student at the Athens University of Economics and Business (AUEB), Department of Management Science and Technology. 20 | 21 | In the summer of 2013, he helped in a research project regarding the evolution of prices at the Greek Ministry for Development and Competitiveness, under the supervision of [Dr. Prodromidis](http://www.kepe.gr/index.php/el/profil-cb/userprofile/pjprodr), presented the results at the eleventh [DMST Conference](http://fsdet.dmst.aueb.gr/) (13/05/2014); and tutored (TAed) certain microeconomic and macroeconomic review sessions for the freshmen class of 2013-14 at the request of [Dr. Prodromidis](http://www.kepe.gr/index.php/el/profil-cb/userprofile/pjprodr).

How often have you heard 7 | that phrase?

The readability of the speeches 13 | is evaluated with the use of the “Simple Measure of Gobbledygook” 14 | (SMOG) formula, partially adjusted to the Greek language. The 15 | sentiment mining is achieved with the use of two Greek sentiment 16 | lexicons. Our findings indicate a significant drop on the average 17 | readability score of the parliament records from 2003 up to 2017. On 18 | the other hand, the sentiment analysis presents steady scores 19 | throughout the years. The communication among parliament members is 20 | characterized mainly by the feeling of surprise followed closely by 21 | anger and disgust.

The results are presented 23 | in graphs, mainly in comparison between political parties as well as 24 | between time intervals. 25 | -------------------------------------------------------------------------------- /content/seminars/2025-01-13.md: -------------------------------------------------------------------------------- 1 | title: Prompt Stability Scoring for Text Annotation with Large Language Models 2 | date: 2025-01-13 3 | presenter: Christopher Barrie, NYU 4 | category: seminars 5 | time: 17:30 6 | 7 | Researchers are increasingly using language models (LMs) for text annotation. These approaches rely only on a prompt telling the model to return a given output according to a set of instructions. The reproducibility of LM outputs may nonetheless be vulnerable to small changes in the prompt design. This calls into question the replicability of classification routines. To tackle this problem, researchers have typically tested a variety of semantically similar prompts to determine what we call "prompt stability." These approaches remain ad-hoc and task specific. In this article, we propose a general framework for diagnosing prompt stability by adapting traditional approaches to intra- and inter-coder reliability scoring. We call the resulting metric the Prompt Stability Score (PSS) and provide a Python package PromptStability for its estimation. Using six different datasets and twelve outcomes, we classify >150k rows of data to: a) diagnose when prompt stability is low; and b) demonstrate the functionality of the package. We conclude by providing best practice recommendations for applied researchers. 8 | 9 | Bio: Christopher Barrie is Assistant Professor of Sociology at NYU.

To evaluate Fuzzol, we test 33 of the latest solc stable re- 17 | leases, and compare fuzzol with (1) Superion, a grammar-aware fuzzer, 18 | (2) AFL-compiler-fuzzer, a text-mutation fuzzer and (3) two grammar-blind 19 | fuzzers with advanced test input generation schedules: AFLFast 20 | and MOpt-AFL. fuzzol identified 19 bugs in total (7 of which were previously 21 | unknown to Solidity developers), while the other fuzzers missed 22 | half of these bugs. 23 | 24 | This work has been accepted at ESORICS '23 and will be presented in September 2023. 25 | -------------------------------------------------------------------------------- /content/seminars/2022-08-22.md: -------------------------------------------------------------------------------- 1 | title: Permanent and ephemeral linking in scientific publishing 2 | presenter: Diomidis Spinellis 3 | date: 2022-08-22 4 | category: seminars 5 | 6 | The world-wide web has allowed scientific publications to include links 7 | to resources available in it via URLs. 8 | Previous research has show that the availability of resources identified 9 | by URLs is ephemeral, decaying with the passage of time. 10 | As a response to the problem of URL decay more permanent identifiers, 11 | such as DOIs, have been developed and are often used. 12 | 13 | I describe the methods and first findings of an ongoing study on the 14 | evolution of web and DOI linking in scientific publications. 15 | The study is based on processing a collection of 16 | n-grams collected from 71 million documents on a small cluster of computers. 17 | Preliminary results indicate that the density of published links per 18 | document has increased 10 × over the past quarter century, 19 | but the percentage of DOIs has also been increasing to reach 20% in 2018. 20 | Looking at failures, I find the expected increase of URL failures 21 | as years go by. 22 | The DOI failures are surprising and warrant further closer investigation. 23 | 24 | As an aside, I also looked at the feasibility of recreating documents 25 | from the n-grams via the Eulerian path approach used for stitching together 26 | DNA fragments. 27 | However, I reached the conclusion that there are too many candidate paths 28 | to do this deterministically. 29 | -------------------------------------------------------------------------------- /content/seminars/2021-04-22.md: -------------------------------------------------------------------------------- 1 | title: Data-Oriented Differential Testing of Object-Relational Mapping Systems 2 | presenter: Thodoris Sotiropoulos 3 | date: 2021-04-22 4 | category: seminars 5 | 6 | 7 | We introduce, 8 | what is to the best of our knowledge, 9 | the first approach 10 | for systematically testing 11 | Object-Relational Mapping (ORM) systems. 12 | Our approach leverages 13 | differential testing to establish a 14 | test oracle for ORM-specific bugs. 15 | Specifically, we first generate random relational database schemas, 16 | set up the respective databases, 17 | and then, we query these databases using the APIs of 18 | the ORM systems under test. To tackle the challenge 19 | that ORMs lack a common input language, 20 | we generate queries written in an abstract query language. These abstract 21 | queries are translated into concrete, executable ORM queries, which are 22 | ultimately used to differentially test the correctness of target implementations. 23 | The effectiveness of our method heavily relies on the data 24 | inserted to the underlying databases. Therefore, we employ a solver-based 25 | approach for producing targeted database records with respect to 26 | the constraints of the generated queries. 27 | We implement our approach as a tool, called CYNTHIA, 28 | which found 28 bugs in five popular ORM systems. 29 | The vast majority of these bugs are confirmed 30 | (25 / 28), 31 | more than half were fixed (20 / 28), 32 | and three were marked as release blockers by the corresponding developers. 33 | -------------------------------------------------------------------------------- /content/seminars/2020-11-27.md: -------------------------------------------------------------------------------- 1 | title: Detecting Locations in JavaScript Programs Affected by Breaking Library Changes 2 | presenter: Anders Møller, Benjamin Barslev Nielsen, Martin Toldam Torp 3 | date: 2020-11-27 4 | category: seminars 5 | 6 | JavaScript libraries are widely used and evolve rapidly. When adapting client code to non-backwards compatible changes in libraries, a major challenge is how to locate affected API uses in client code, which is currently a difficult manual task. In this paper we address this challenge by introducing a simple pattern language for expressing API access points and a pattern-matching tool based on lightweight static analysis. 7 | 8 | Experimental evaluation on 15 popular npm packages shows that typical breaking changes are easy to express as patterns. Running the static analysis on 265 clients of these packages shows that it is accurate and efficient: it reveals usages of breaking APIs with only 14% false positives and no false negatives, and takes less than a second per client on average. In addition, the analysis is able to report its confidence, which makes it easier to identify the false positives. These results suggest that the approach, despite its simplicity, can reduce the manual effort of the client developers. 9 | 10 | This is a paper presented at this year's OOPSLA (Object-Oriented Programming, Systems, Languages & Applications) conference and recommended for the seminar by Theodoris Sotiropoulos. We will watch the talk's video and then discuss the method, the results, and the paper. 11 | --------------------------------------------------------------------------------
