averloc (AdVERsarial Learning On Code)

Repository for Semantic Robustness of Models on Source Code.

Directory Structure

In this repository, we have the following directories:

./datasets

Note: the datasets are all much too large to be included in this GitHub repo. This is simply the structure as it would exist on disk once our framework is setup.

./datasets
  + ./raw            # The four datasets in "raw" form
  + ./normalized     # The four datasets in the "normalized" JSON-lines representation 
  + ./preprocess
    + ./tokens       # The four datasets in a representation suitable for token-level models
    + ./ast-paths    # The four datasets in a representation suitable for code2seq
  + ./transformed    # The four datasets transformed via our code-transformation framework 
    + ./normalized   # Transformed datasets normalized back into the JSON-lines representation
    + ./preprocessed # Transformed datasets preprocessed into:
      + ./tokens     # ... a representation suitable for token-level models
      + ./ast-paths  # ... a representation suitable for code2seq
  + ./adversarial    # Datasets in the format < source, target, tranformed-variant #1, #2, ..., #K >
    + ./tokens       # ... in a token-level representation
    + ./ast-paths    # ... in an ast-paths representation

./models

We have two Machine Learning on Code models. Both of them are trained on the Code Summarization task. The seq2seq model has been modified to include an adversarial training loop and a way to compute Integrated Gradients. The code2seq model has been modified to include an adversarial training loop and emit attention weights.

./models
  + ./code2seq         # seq2seq model implementation
  + ./pytorch-seq2seq  # code2seq model implementation

./results

This directory stores results that are small-enough to be checked into GitHub. In addition, a few utility scripts live here.

./scratch

This directory contains exploratory data analysis and evaluations that did not fit into the overall workflow of our code-transformation + adversarial training framework. For instance, HTML-based visualizations of Integrated Gradients and attention exist in this directory.

./scripts

In this directory there are a large number of scripts for doing various chores related to running and maintaing this code transformation infrastructure.

./tasks

This directory houses the implementations of various pieces of our core framework:

./tasks
  + ./astor-apply-transforms
  + ./depth-k-test-seq2seq
  + ./download-c2s-dataset
  + ./download-csn-dataset
  + ./extract-adv-dataset-c2s
  + ./extract-adv-dataset-tokens
  + ./generate-baselines
  + ./integrated-gradients-seq2seq
  + ./normalize-raw-dataset
  + ./preprocess-dataset-c2s
  + ./preprocess-dataset-tokens
  + ./spoon-apply-transforms
  + ./test-model-code2seq
  + ./test-model-seq2seq
  + ./train-model-code2seq
  + ./train-model-seq2seq

./vendor

This directory contains dependencies in the form of git submodukes.

Makefile

We have one overarching Makefile that can be used to drive a number of the data generation, training, testing, adn evaluation tasks.
