How Simple Can It Get? From Interpretable Equations to Readable Rules for Financial Decision Making

Adia Lumadjeng, Ilker Birbil, Erman Acar

In regulated domains such as finance, a model that cannot be explained cannot be deployed, yet many interpretable classifiers defeat their own purpose by producing formulas with do…

ECSEL: Explainable Classification via Signomial Equation Learning

Adia Lumadjeng, Ilker Birbil, Erman Acar

We introduce ECSEL, an explainable classification method that learns formal expressions in the form of signomial equations, motivated by the observation that many symbolic regressi…

Same Content, Different Answers: Cross-Modal Inconsistency in MLLMs

Angela van Sprang, Laurens Samson, Ana Lucic +3

We introduce two new benchmarks REST and REST+ (Render-Equivalence Stress Tests) to enable systematic evaluation of cross-modal inconsistency in multimodal large language models (M…

Explaining the Explainer: Understanding the Inner Workings of Transformer-based Symbolic Regression Models

Arco van Breda, Erman Acar

Following their success across many domains, transformers have also proven effective for symbolic regression (SR); however, the internal mechanisms underlying their generation of m…

Interpretability for Time Series Transformers using A Concept Bottleneck Framework

Angela van Sprang, Erman Acar, Willem Zuidema

Mechanistic interpretability focuses on reverse engineering the internal mechanisms learned by neural networks. We extend our focus and propose to mechanistically forward engineer…

Successful Misunderstandings: Learning to Coordinate Without Being Understood

Nikolaos Kondylidis, Anil Yaman, Frank van Harmelen +2

The main approach to evaluating communication is by assessing how well it facilitates coordination. If two or more individuals can coordinate through communication, it is generally…
