Exploring AI, mathematical reasoning, and symbolic regression at EPFL

Boolformer
ICML 2025 | Stéphane d'Ascoli*, Arthur Renard*, Emmanuel Abbé, Clément Hongler, Vassilis Papadopoulos, Josh Susskind, Samy Bengio - APPLE, EPFL
We introduce Boolformer, a Transformer-based model trained to perform end-to-end symbolic regression of Boolean functions. The model can predict compact formulas for complex functions not seen during ...

Phase Transition Finder
GECCO 2024 | Vassilis Papadopoulos, Guilhem Doat, Arthur Renard, Clément Hongler - EPFL
One key challenge in Artificial Life is designing systems that display an emergence of complex behaviors. Many such systems depend on a high-dimensional parameter space, only a small subset of which d...
