Researchers have introduced SCOUT, a novel agentic framework designed to improve reasoning over extremely long egocentric videos. SCOUT incorporates a self-checking and recovery-aware policy that dynamically balances exploration and exploitation of video segments. To address challenges in training these agents, the team developed UPS-GRPO, an uncertainty-prioritized policy optimization method that enhances credit assignment for long-horizon decision-making. Experiments demonstrate SCOUT's state-of-the-art performance on ultra-long egocentric video benchmarks. AI
