• Integrated gradients for deep learning
• Kernel SHAP integration
• Contrastive Explanation Method (CEM)
• Trust scores for prediction confidence
• Pertinent positives and negatives
• Prototype and criticism selection

Target Processes

• Model Interpretability and Explainability Analysis
• Model Evaluation and Validation Framework

Tools and Libraries

• Alibi
• Alibi Detect
• TensorFlow/PyTorch
• scikit-learn
