Researchers have developed ReFoCUS, a novel framework that uses reinforcement learning to optimize frame selection for video-based Large Multi-modal Models (LMMs). This approach aims to improve video understanding by learning a policy that identifies semantically relevant frames, rather than relying on static heuristics. ReFoCUS leverages reward signals from reference models to guide frame selection, removing the need for explicit frame-level supervision and demonstrating improved reasoning accuracy on video question-answering benchmarks.
