Transitive Representation Learning Enhances Histopathology Annotation

ICML 2026poster

AI-driven disease characterization in histopathology promises to assist in clinical decision making, but its performance is limited by the scarcity of detailed annotations. In contrast, single-cell gene expression provides expressive and interpretable labels that compensate this scarcity, but assays…

When Flatness Does (Not) Guarantee Adversarial Robustness

ICLR 2026poster

Despite their empirical success, neural networks remain vulnerable to small, adversarial perturbations. A longstanding hypothesis suggests that flat minima, regions of low curvature in the loss landscape, offer increased robustness. While intuitive, this connection has remained largely informal and…

Neural Rule Lists: Learning Discretizations, Rules, and Order in One Go

NeurIPS 2025poster

Interpretable machine learning is essential in high-stakes domains like healthcare. Rule lists are a popular choice due to their transparency and accuracy, but learning them effectively remains a challenge. Existing methods require feature pre-discretization, constrain rule complexity or ordering, o…

Finding Interpretable Class-Specific Patterns through Efficient Neural Search

AAAI 2024technical

Discovering patterns in data that best describe the differences between classes allows to hypothesize and reason about class-specific mechanisms. In molecular biology, for example, these bear the promise of advancing the understanding of cellular processes differing between tissues or diseases, whic…

Learning Exceptional Subgroups by End-to-End Maximizing KL-Divergence

ICML 2024spotlight

Finding and describing sub-populations that are exceptional in terms of a target property has important applications in many scientific disciplines, from identifying disadvantaged demographic groups in census data to finding conductive molecules within gold nanoparticles. Current approaches to findi…
