New RL method teaches LLMs to self-correct answers

Researchers have developed SCoRe, a novel two-stage reinforcement learning technique that enables language models to refine their own responses using self-generated data. This method significantly improves performance on benchmarks like MATH and HumanEval when applied to models such as Gemini 1.5 Flash and 1.0 Pro. Additionally, a separate study explored process versus outcome supervision for mathematical reasoning, finding that process-reward models yield better results, though the advantage diminishes with fewer samples.

    SCoRe is a two-stage on-policy RL recipe that teaches a language model to revise its own answers using only self-generated data. On Gemini 1.5 Flash and 1.0 Pro it gains 15.6 points on MATH and 9.1 on HumanEval over the base model. At matched inference budgets, sequential self-co…
