Generalization of RLVR Using Causal Reasoning as a Testbed

Researchers studied reinforcement learning with verifiable rewards (RLVR) for training large language models on causal reasoning tasks, finding it outperforms supervised fine-tuning but only when models have sufficient initial competence. The study used causal graphical models as a testbed and showed RLVR improves specific reasoning subskills like marginalization strategy and probability calculations.

Diagnosing Generalization Failures from Representational Geometry Markers

Researchers propose a new approach to predict AI model failures by analyzing geometric properties of data representations rather than reverse-engineering internal mechanisms. They found that reduced manifold dimensionality and utility in training data consistently predict poor performance on out-of-distribution tasks across different architectures and datasets.

BeamPERL: Parameter-Efficient RL with Verifiable Rewards Specializes Compact LLMs for Structured Beam Mechanics Reasoning

Researchers trained a compact 1.5B parameter language model to solve beam physics problems using reinforcement learning with verifiable rewards, achieving 66.7% improvement in accuracy. However, the model learned pattern-matching templates rather than true physics reasoning, failing to generalize to topological changes despite mastering the same underlying equations.
