1 | # H2O generated POJO model WebApp Example
2 |
3 | This example shows a generated Java POJO being called using a REST API from a JavaScript Web application.
4 |
5 | The application simulates the experience of a consumer applying for a loan. The consumer provides some information about themselves and is either offered a loan or denied.

49 | ## Steps to run
50 |
51 | ##### Step 1: Create the gradle wrapper to get a stable version of gradle.
52 |
53 | ```
54 | $ gradle wrapper
55 | ```
56 |
57 | ##### Step 2: Install H2O's R package if you don't have it yet.
58 |
59 |
60 |
61 | ##### Step 3: Build the project.
62 |
63 | ```
64 | $ ./gradlew build # Run R script to generate POJOs
65 | $ ./gradlew build -PusePython=true # Run Python script to generate POJOs
66 | ```
67 |
68 | ##### Step 4: Deploy the .war file in a Jetty servlet container.
69 |
70 | ```
71 | $ ./gradlew jettyRunWar -x generateModels
72 | ```
73 |
74 | (If you don't include the -x generateModels above, you will build the models again, which is time consuming.)
75 |
76 | ##### Step 5: Visit the webapp in a browser.
77 |
78 |
79 |
80 |
81 | ## Underneath the hood
82 |
83 | Make a prediction with curl and get a JSON response.
84 |
85 | ```
86 | $ curl "localhost:8080/predict?loan_amnt=10000&term=36+months&emp_length=5&home_ownership=RENT&annual_inc=60000&verification_status=verified&purpose=debt_consolidation&addr_state=FL&dti=3&delinq_2yrs=0&revol_util=35&total_acc=4&longest_credit_length=10"
87 | {
88 | "labelIndex" : 0,
89 | "label" : "0",
90 | "classProbabilities" : [
91 | 0.8581645524025798,
92 | 0.14183544759742012
93 | ],
94 |
95 | "interestRate" : 12.079950220424134
96 | }
97 | ```
98 |
99 | Notes:
100 |
101 | * classProbabilities[1] is .1418. This is the probability of a bad loan.
102 | * The threshold is the max-F1 calculated for the model, in this case approximately .20.
103 | * A label of '1' means the loan is predicted bad.
104 | * A label of '0' means the loan is not predicted bad.
105 | * If the loan is not predicted bad, then use the interest rate prediction to suggest an offered rate to the loan applicant.
106 |
107 |
108 | ```
109 | $ curl "localhost:8080/predict?loan_amnt=10000&term=36+months&emp_length=5&home_ownership=RENT&annual_inc=60000&verification_status=blahblah&purpose=debt_consolidation&addr_state=FL&dti=3&delinq_2yrs=0&revol_util=35&total_acc=4&longest_credit_length=10"
110 | [... HTTP error response simplified below ...]
111 | Unknown categorical level (verification_status,blahblah)
112 | ```
113 |
114 |
115 | ## Performance
116 |
117 | 1. Set VERBOSE to false in src/main/java/org/gradle/PredictServlet.java
118 |
119 | 1. ./gradlew jettyRunWar -x war
120 |
121 | 1. Run apachebench as shown here:
122 |
123 | ```
124 | $ ab -k -c 8 -n 10000 "localhost:8080/predict?loan_amnt=10000&term=36+months&emp_length=5&home_ownership=RENT&annual_inc=60000&verification_status=VERIFIED+-+income&purpose=debt_consolidation&addr_state=FL&dti=3&delinq_2yrs=0&revol_util=35&total_acc=4&longest_credit_length=10"

188 | ## Data
189 |
190 | The original data can be downloaded at and it is all the data from 2007 to June 30, 2015. This does not incorporate the declined loan data set which does not have the same feature set. Note that some munging was done to distill the data to what is in this git repository.
