We improve the quality of feature attributions by optimally combining multiple explanation methods. Our convex-combination strategy enhances robustness and faithfulness, consistently outperforming individual methods and baselines across architectures. Published at the International Conference on Machine Learning.

This work compiles a domain-agnostic taxonomy of pitfalls in validation metrics, based on a multistage Delphi process and community feedback. It offers practical guidance to improve evaluation practices across application domains.

We present Metrics Reloaded, a comprehensive framework for problem-aware selection of evaluation metrics in biomedical image analysis. Developed through a large international Delphi process, it introduces the concept of a problem fingerprint to guide researchers toward meaningful and domain-relevant validation.

Our latest work introduces the first bias–variance–covariance decomposition for kernel scores, providing a unified framework for uncertainty estimation in generative models. We show how kernel-based entropy and variance capture uncertainty across image, audio, and language generation — even in closed-source models.
