Informative Perturbation Selection for Uncertainty-Aware Post-hoc Explanations
🤖AI Summary
Researchers introduce EAGLE, a new framework for explaining black-box machine learning models using information-theoretic active learning to select optimal data perturbations. The method produces feature importance scores with uncertainty estimates and demonstrates improved explanation reproducibility and stability compared to existing approaches like LIME.
Key Takeaways
- →EAGLE formulates perturbation selection as an active learning problem to efficiently learn surrogate models for ML explanation.
- →The framework provides both feature importance scores and confidence estimates for better uncertainty quantification.
- →Theoretical analysis shows cumulative information gain scales as O(d log t) where d is feature dimension and t is sample count.
- →Empirical results demonstrate improved explanation reproducibility and neighborhood stability versus state-of-the-art baselines.
- →The method addresses trust and ethical concerns in deployed opaque machine learning systems through better post-hoc explanations.
