PRISM: Pushing the Frontier of Deep Think via Process Reward Model-Guided Inference

Researchers introduce PRISM, a new AI inference algorithm that uses Process Reward Models to guide deep reasoning systems. The method significantly improves performance on mathematical and scientific benchmarks by treating candidate solutions as particles in an energy landscape and using score-guided refinement to concentrate on higher-quality reasoning paths.

Efficient Process Reward Modeling via Contrastive Mutual Information

Researchers propose CPMI, an automated method for training process reward models that reduces annotation costs by 84% and computational overhead by 98% compared to traditional Monte Carlo approaches. The technique uses contrastive mutual information to assign reward scores to reasoning steps in AI chain-of-thought trajectories without expensive human annotation or repeated LLM rollouts.
