Session
The advancement of AI systems necessitates the need for interpretability to address transparency, biases, risks, and regulatory compliance. The workshop teaches core techniques in interpretability, including SHAP (game-theoretic feature attribution), GINI (decision tree impurity analysis), LIME (local surrogate models), and Permutation Importance (feature shuffling), which provide global and local explanations for model decisions. With hands-on building of interpretability tools and visualization techniques, we explore how these methods enable bias detection and clinical trust in healthcare diagnostics and develop the most effective strategies in finance. These techniques are essential in building interpretable AI to address the challenges of the black-box models.
