PyExplainer 
PyExplainer is a local rule-based model-agnostic technique for generating explanations (i.e., why a commit is predicted as defective) of Just-In-Time (JIT) defect prediction defect models.
Through a case study of two open-source software projects, we find that our PyExplainer produces (1) synthetic neighbous that are 41%-45% more similar to an instance to be explained; (2) 18%-38% more accurate local models; and (3) explanations that are 69%-98% more unique and 17%-54% more consistent with the actual characteristics of defect-introducing commits in the future than LIME (a state-of-the-art model-agnostic technique).

Quick Start
You can try our PyExplainer directly without installation at this online JupyterNotebook (just open and run TUTORIAL.ipynb). The tutorial video below demonstrates how to use our PyExplainer in this JupyterNotebook.
In the JupyterNotebook:
- Run cells from step 1 to step 3 to create an interactive visualization in jupyter notebook cell (like the example above). You can change the input feature values of ML model at slide bar.
- Run the cells in appendix section if you would like to get more detail about variable used to build PyExplainer
See the instructions below how to install our PyExplainer Python Package.
