LLM-as-a-Judge framework boosts AI reasoning with novel reward system

Researchers have developed a novel semi-supervised learning framework that utilizes a Large Language Model (LLM) as a judge to distill knowledge into AI models. This approach employs a continuous Chain-of-Thought (CoT) reward, calculated from a judge LLM's output, to provide an effective training signal for unlabeled data. The framework demonstrates performance comparable to or exceeding methods relying on ground-truth rewards, especially with increased unlabeled data. Combining this LLM-based reward with verifiable rewards in a semi-supervised setup proves synergistic, enhancing mathematical reasoning capabilities by 5-10% across various tasks and model architectures.
