Researchers have introduced Reflect-R1, a novel framework designed to enhance self-correction in long video understanding models. This system addresses the issue of models becoming overconfident due to a lack of external evidence by incorporating an evidence-driven approach. Reflect-R1 employs a three-stage pipeline: intuition, verification, and arbitration, which dynamically retrieves visual evidence to validate initial assessments and resolve conflicts, thereby preventing hallucinations. To tackle reinforcement learning complexities in multi-stage pipelines, a stage-decoupled algorithm named SD-GRPO was developed, alongside a new dataset of 120,000 samples to facilitate training. Experiments on benchmarks like VideoMME and LongVideoBench show Reflect-R1 achieving state-of-the-art results by significantly improving genuine rectification rates. AI
