JITLine: A Simpler, Better, Faster, Finer-grained Just-In-Time Defect Prediction

The source code that we used to perform experiment in "JITLine: A Simpler, Better, Faster, Finer-grained Just-In-Time Defect Prediction" paper.

Please run the jupyter notebook following the steps below to reproduce our experiment.

1. run code in JITLine_commit_level.ipynb to train commit-level model
2. run code in JITLine_line_level.ipynb to train line-level model
3. run code in JITLine_commit_level_eval.ipynb and JITLine_line_level_eval.ipynb to obtain experiment result

We also provide the commit features that we used in our study, which can be found in commit_change_features.pdf
