Researchers have introduced SCARL, a novel reinforcement learning technique designed to improve language model reasoning. SCARL addresses the issue of confidence misalignment in reinforcement learning with verifiable rewards (RLVR) by aligning a policy's confidence in a response with its actual reward. This method aims to ensure that responses the model is highly confident about are also those that receive higher rewards, and vice versa. Experiments show SCARL improves performance on benchmarks like Pass@32 and enhances both coverage and per-draw accuracy across various estimators and model backbones, while also preserving policy entropy.
