PyExplainer: Explaining the Predictions of Just-In-Time Defect Models

Just-In-Time (JIT) defect prediction (i.e., an AI/ML model to predict defect-introducing commits) is proposed to help developers prioritize their limited Software Quality Assurance (SQA) resources on the most risky commits. However, the explainability of JIT defect models remains largely unexplored (i.e., practitioners still do not know why a commit is predicted as defect-introducing). Recently, L...
