Label-Free Reinforcement Learning via Cross-Model Entropy

Researchers propose Cross-Model Entropy (CME), a label-free reward signal for reinforcement learning that uses a separate verifier model's likelihood assessment instead of human labels or self-referential signals. The method successfully extends RL post-training to open-ended instruction following across multiple model families, achieving win rates of 52.5-71.4% in head-to-head comparisons.

FoundObj: Self-supervised Foundation Models as Rewards for Label-free 3D Object Segmentation

FoundObj introduces a self-supervised framework for 3D object segmentation in point clouds without manual scene-level annotations, using reinforcement learning guided by semantic and geometric reward modules from foundation models. The approach demonstrates strong performance across benchmarks and shows particular promise in zero-shot and long-tail scenarios, advancing label-free computer vision capabilities.
