Automated Molecular Concept Generation and Labeling with Large Language Models

COLING 2025main

Artificial intelligence (AI) is transforming scientific research, with explainable AI methods like concept-based models (CMs) showing promise for new discoveries. However, in molecular science, CMs are less common than black-box models like Graph Neural Networks (GNNs), due to their need for predefi…

The Unreasonable Effectiveness of Entropy Minimization in LLM Reasoning

NeurIPS 2025poster

Entropy minimization (EM) trains the model to concentrate even more probability mass on its most confident outputs. We show that this simple objective alone, without any labeled data, can substantially improve large language models’ (LLMs) performance on challenging math, physics, and coding tasks.…
