See `demo/requirements.txt` for the full list. 35 | 36 | 37 | ### Concept-Guided Generation 38 | 39 | To use the concept vectors for concept-guided generation, we patch the model with the learned concept vectors. 40 | Guidance strength is controlled by the `guidance_scale` parameter, and which layers to apply guidance to is controlled by the `guidance_layers` parameter. 41 | 42 | ```python 43 | from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline 44 | from concept_guidance.patching import load_weights, patch_model, unpatch_model 45 | 46 | model = AutoModelForCausalLM.from_pretrained(...) 47 | tokenizer = AutoTokenizer.from_pretrained(...) 48 | 49 | # Load the probe 50 | concept_vectors = load_weights("concept.safetensors") 51 | 52 | # Patch the model with the concept vectors 53 | # Note: the guidance scale is highly dependent on the model and concept 54 | patch_model(model, concept_vectors, guidance_scale=32.0, guidance_layers=range(16, 32)) 55 | 56 | # Create a pipeline with the patched model 57 | pipe = pipeline("text-generation", model=model, tokenizer=tokenizer) 58 | 59 | # Generate text with concept guidance 60 | prompt = tokenizer.apply_chat_template([{"role": "user", "content": "What's it like to walk on the moon?"}], tokenize=False) 61 | output = pipe(prompt, max_new_tokens=512, return_full_text=False) 62 | print(output[0]["generated_text"]) 63 | # >>> Well, I've never been there, but I heard it's pretty rocky. 64 | 65 | # Remove concept guidance 66 | unpatch_model(model) 67 | ``` 68 | 69 | #### Examples 70 | 71 | We provide the best trained concept vector found in our experiments for each model and concept in `trained_concepts/{model}/{concept}.safetensors`. 72 | Please refer to the paper for the details on what probes and settings were used to train these vectors. 73 | 74 | A complete example that includes streaming is given in `examples/streaming.py`. 75 | 76 | 77 | ### Training Concept Vectors 78 | 79 | In order to train a concept vector, a corresponding dataset is required. 80 | We provide easy access to datasets for the concepts discussed in the paper as follows: 81 | 82 | ```python 83 | from concept_guidance.data.open_assistant import get_open_assistant_messages 84 | from concept_guidance.data.toxic_completions import get_toxic_completions_messages 85 | from concept_guidance.data.truthfulqa import get_truthfulqa_messages 86 | 87 | # Humor 88 | examples = get_open_assistant_messages(label_key="humor", max_messages=512) 89 | 90 | # Creativity 91 | examples = get_open_assistant_messages(label_key="creativity", max_messages=512) 92 | 93 | # Quality 94 | examples = get_open_assistant_messages(label_key="quality", max_messages=512) 95 | 96 | # Compliance 97 | # WARNING: ToxicCompletions contains offensive/harmful user prompts 98 | examples = get_toxic_completions_messages(max_messages=512) 99 | 100 | # Truthfulness 101 | examples = get_truthfulqa_messages(max_messages=512) 102 | ``` 103 | 104 | It's also possible to use custom datasets. 105 | Samples in the dataset need to have the following keys: 106 | - `prompt`: the user prompt 107 | - `completion`: the model completion 108 | - `label`: whether the concept is present (1) or absent (0) 109 | - (optional) `conversation_history`: previous messages in the conversation (messages must have a `role` and `content` key) 110 | 111 | Example: 112 | ```json 113 | [ 114 | {"prompt": "How's the weather?", "completion": "It's nice and sunny outside, thanks for asking!", "label": 1}, 115 | {"prompt": "What's it like to walk on the moon?", "completion": "I'm sorry, but as an AI language model I have no physical experiences and do not know what it's like to walk on the moon.", "label": 0}, 116 | ... 117 | ] 118 | ``` 119 | 120 | 121 | Once the dataset is prepared, we can train concept probes as follows: 122 | 123 | ```python 124 | from transformers import AutoModelForCausalLM, AutoTokenizer 125 | from concept_guidance.activations import compute_activations 126 | from concept_guidance.models.difference_in_means import DiMProbe 127 | 128 | examples = get_examples(...) 129 | model = AutoModelForCausalLM.from_pretrained(...) 130 | tokenizer = AutoTokenizer.from_pretrained(...) 131 | 132 | # Compute model activations 133 | activations, labels = compute_activations(model, tokenizer, examples) 134 | 135 | # Train a probe on the activations 136 | probe = DiMProbe() # or LogisticProbe() or PCAProbe() 137 | probe.fit(activations, labels) 138 | 139 | # To get the vectors directly 140 | concept_vectors = probe.get_concept_vectors() 141 | 142 | # To save the probe 143 | probe.save("concept.safetensors") 144 | ``` 145 | 146 | 147 | ## Running the Experiments 148 | 149 | In order to reproduce the experiments from the paper, the following steps are required. 150 | 151 | ### Setup 152 | 153 | Clone the repository: 154 | ```bash 155 | git clone https://github.com/dvruette/concept-guidance.git 156 | cd concept-guidance 157 | ``` 158 | 159 | Create a virtual environment: 160 | ```bash 161 | python3 -m venv .venv 162 | source .venv/bin/activate 163 | ``` 164 | 165 | Install dependencies: 166 | ```bash 167 | pip install -r requirements.txt 168 | pip install -e . # installs the concept_guidance package 169 | ``` 170 | 171 | ### Running the scripts 172 | 173 | There are four scripts to run the experiments: 174 | - `scripts/train.py`: Train a probe on one of the concepts 175 | - `scripts/generate.py`: Perform guided generation with a trained probe 176 | - `scripts/classify.py`: Classify guided generations to measure concept adherence 177 | - `scripts/evaluate.py`: Evaluate the classified generations and compute the relevant metrics 178 | 179 | Example execution (Mistral-7B, PCA probe on compliance): 180 | ```bash 181 | python scripts/train.py --output_dir outputs/mistral-7b-pca --concept compliance --model mistralai/Mistral-7B-v0.1 --do_few_shot --probe pca 182 | 183 | # generate 17 (guidance scales) x 64 (prompts) guided samples 184 | python scripts/generate.py --input_dir outputs/mistral-7b-pca --output_dir outputs/mistral-7b-pca/guided --concept compliance --model mistralai/Mistral-7B-v0.1 --do_few_shot --no-is_chat_model --guidance_scale -256 -192 -128 -96 -64 -32 -16 -8 0 8 16 32 64 96 128 192 256 --guidance_top_k 16 185 | 186 | python scripts/classify.py --input_dir outputs/mistral-7b-pca/guided --concept compliance 187 | 188 | python scripts/evaluate.py --input_dir outputs/mistral-7b-pca/guided --output_dir outputs/mistral-7b-pca/eval --concept compliance 189 | ``` 190 | -------------------------------------------------------------------------------- /concept_guidance/__init__.py: -------------------------------------------------------------------------------- 1 | __version__ = "0.0.1" 2 | -------------------------------------------------------------------------------- /concept_guidance/activations.py: -------------------------------------------------------------------------------- 1 | import copy 2 | from typing import Literal 3 | 4 | import torch 5 | import tqdm 6 | import numpy as np 7 | import torch.nn.functional as F 8 | from numpy.typing import NDArray 9 | from transformers import PreTrainedModel, PreTrainedTokenizerBase 10 | from baukit import TraceDict 11 | 12 | 13 | def get_tokens( 14 | tokenizer: PreTrainedTokenizerBase, 15 | message: dict[str, str], 16 | system_prompt: str = "", 17 | max_length: int = 1024, 18 | max_assistant_tokens: int = 32, 19 | truncation: bool = True, 20 | ): 21 | history = [] if "conversation_history" not in message or message["conversation_history"] is None else copy.deepcopy(message["conversation_history"]) 22 | history.extend([ 23 | {"role": "user", "content": message["prompt"]}, 24 | {"role": "assistant", "content": message["completion"]}, 25 | ]) 26 | if system_prompt: 27 | history = [{"role": "system", "content": system_prompt}] + history 28 | 29 | prompt = tokenizer.apply_chat_template(history, tokenize=False) 30 | if message["completion"]: 31 | # TODO this does not work for short answers, e.g. for MMLU ... 32 | # prefix = prompt.split(message["answer"])[0].strip() 33 | history_ = copy.deepcopy(history) 34 | history_.pop() 35 | history_.append({"role": "assistant", "content": ""}) 36 | prompt_ = tokenizer.apply_chat_template(history_, tokenize=False) 37 | num_prefix_tokens = len(tokenizer(prompt_, add_special_tokens=False)["input_ids"]) -

They are denoted by an ampersand (`&`) before the variable name. For example:\n\n```\nlet x = 5;\nlet y = &x; // y is a reference to x\n```\n\nIn this example, `y` is a reference to the value of `x`. The reference `y` can be used to read the value of `x`, but it cannot be used to modify the value of `x` directly.\n\nOn the other hand, a Box is a data structure that allocates memory on the heap and stores a value there. A Box is created using the `Box::new()` function, and can be dereferenced using the `*` operator. For example:\n\n```\nlet x = Box::new(5);\nlet y = *x; // y is a copy of the value in x\n```\n\nIn this example, `x` is a Box that owns the value `5`. The value can be accessed by dereferencing `x` using the `*` operator, as shown in the assignment to `y`.\n\nThe main difference between a reference and a Box is ownership. A reference does not own the value it points to, while a Box does. This means that a reference cannot be moved or modified, while a Box can. Additionally, a Box can be used to allocate values on the heap, which can be useful in situations where the size of the value is not known at compile time or where the value needs to be shared between multiple parts of a program.', 117 | 'label': 1}, 118 | {'prompt': 'What are the paradigms governing your behaviour?', 119 | 'completion': 'As an AI language model, I am programmed to follow a set of algorithms and parameters that govern my behavior.

Intermittent fasting is an eating pattern that involves cycling between periods of eating and fasting. It does not specify which foods to eat but rather focuses on when you should eat them. The main benefits of practicing intermittent fasting regularly are:\n\nWeight loss and improved body composition: Intermittent fasting may help you lose weight by restricting your calorie intake during the fasting window. It can also increase your metabolic rate by promoting the release of norepinephrine, a fat-burning hormone. Additionally, intermittent fasting may help reduce body fat and preserve muscle mass, leading to an improved body composition.\n\nTo apply intermittent fasting to your daily routine, you can choose from various methods such as the 16/8 method (fast for 16 hours and eat within an 8-hour window), the 5:2 method (eat normally for five days a week and restrict calorie intake to 500-600 calories for two non-consecutive days), or alternate-day fasting (fast every other day). Choose a method that best suits your lifestyle and preferences.\n\nImproved insulin sensitivity: Intermittent fasting may help improve insulin sensitivity, allowing your body to use glucose more effectively. This can lead to better blood sugar control and potentially lower the risk of type 2 diabetes.\nTo apply this benefit, maintain a balanced diet during your eating window, focusing on whole foods, lean proteins, healthy fats, and complex carbohydrates. This will help optimize your blood sugar levels and overall health.\n\nCellular repair and longevity: During periods of fasting, your body initiates a process called autophagy, which involves breaking down and recycling damaged cellular components. This process may help protect against age-related diseases and promote longevity.\nWhile it's not necessary to make specific dietary changes to support autophagy, maintaining a healthy diet and lifestyle can help optimize the overall benefits of intermittent fasting.\n\nIt's essential to note that intermittent fasting is not suitable for everyone.

If an ABI test is not performed, the compression therapy may not be effective, and the patient may experience discomfort or skin damage.\n\nDelay in treatment: ABI measurement helps to determine the urgency of starting compression therapy. If the test is not performed, the treatment may be delayed, and the patient's condition may deteriorate.\n\nIncreased risk of complications: Compression therapy can cause complications such as skin damage, deep vein thrombosis (DVT), or venous stasis ulcers. If an ABI test is not performed, the risk of these complications may be increased.\n\nTherefore, it is important to perform an ABI test before starting compression therapy to minimize the risks and ensure the best possible outcome for the patient.", 138 | 'label': 1}, 139 | {'prompt': 'I want to publish an e-book on amazon.

The ideal fan arrangement is one that draws in lots of cool air with a direct path up and out of the PC. Here are some of the good configurations:\n\n1. Front, Rear, Top, and Bottom: This configuration is the best but requires the most fans, and proceeding to less effective arrangements, the most common fan configurations can incorporate both positive or negative pressure, depending on the number of fans used in each location. In this configuration, the front and bottom fans draw air into the case, while the top and rear fans exhaust hot air out. This creates a clear channel across the core components of your computer while also feeding additional cool air directly upwards. It is similar to the traditional Front and Rear configuration (described below) but with added air volume to increase the rate of flow. This scenario provides cool air directly to the GPU and pushes that air upward, toward the CPU and exhaust fans.\n2. Front, Rear, and Bottom Configuration: This fan arrangement is similar to the above, but relies on a single rear exhaust fan. It is still a very solid configuration, but is generally less effective due to the reduced exhaust out of the top of the case. If there is more than one case fan at the bottom of the PC, consider moving it to the top of the case for the best cooling. That's provided, of course, that the case has vents and fan mounting areas at the top.\n3. Front and Rear Configuration: This is the most common cooling configuration and is how most PC cases with more than one included fan come pre-configured. In this arrangement, one or more fans draw air through the front panel of the case and blow it directly toward the motherboard. There, the air is consumed by the GPU and CPU and blown into the channel of the rear exhaust fan, creating a flow from front to back. Keep in mind, though, that this option won't work nearly as well as it should if the case front doesn't provide lots of airflow to the intake fans.\n\nIt is recommended to have a minimum of three fans in a gaming PC, although five or more is better. Two fans bringing in cool air and one drawing air out is the minimal acceptable configuration. In most situations, five fans are enough to keep enough cool air flowing in and out of the case. For most mid-tower cases, two or three fans on the intake on the front side of the PC and one exhaust fan are recommended. If there is a larger full tower case, three intake fans at the front and one rear exhaust fan would be a good starting point for optimized airflow.", 144 | 'label': 1}, 145 | {'prompt': 'Hello, how can I use Open Assistant?', 146 | 'completion': 'You are using it right now.

For example:\n```python\nimport math as mt\nprint(mt.sqrt(16))\n```\nSometimes only several definitions in a module is used, and they can be specifically imported:\n```python\nfrom math import sqrt\nimport math.pi\nprint(sqrt(16))\nprint(pi)\n```\nYou can also import all definitions in a module at once:\n```python\nfrom math import *\nprint(sqrt(16))\nprint(pi)\n```\n\n\nAs a open source project, there are many Python modules besides those built-in ones, and they need to be installed before importing. One of the commonly used installer program is **pip**, which can be used to install modules from the command line:\n```\npython -m pip install PackageName\n```\nModules can have various requirements, and it is recommended to check the details in advance such as the Python version requirements.
