The paper "Towards Robust Interpretability with Self-Explaining Neural Networks" by David Alvarez-Melis and Tommi S. Jaakkola from MIT's CSAIL addresses the challenge of interpretability in complex machine learning models. The authors propose a new class of models called *self-explaining* models, which are designed to be interpretable during the learning process itself, rather than relying on post-hoc explanations. These models aim to satisfy three key criteria for interpretability: explicitness, faithfulness, and stability.
The authors start by discussing the limitations of existing interpretability methods, which often fail to meet these criteria. They then present a step-by-step approach to designing self-explaining models, starting from simple linear classifiers and gradually generalizing to more complex models while maintaining architectural clarity. Regularization techniques are used to enforce the desired properties of interpretability.
The main contributions of the paper include:
1. A rich class of interpretable models where explanations are intrinsic to the model.
2. Three desiderata for explanations (explicitness, faithfulness, and stability) and an optimization procedure to enforce them.
3. Quantitative metrics to evaluate whether models adhere to these principles.
The paper also includes experimental results on various benchmark datasets, demonstrating that the proposed framework offers a promising direction for balancing model complexity and interpretability. The authors conclude by discussing the potential extensions and applications of their work.The paper "Towards Robust Interpretability with Self-Explaining Neural Networks" by David Alvarez-Melis and Tommi S.
