Researchers have introduced SceneBench, a new benchmark designed to evaluate video understanding models' ability to retain context over long videos, particularly across different scenes. Their findings indicate that current vision-language models (VLMs) exhibit significant forgetting when asked questions that require reasoning over extended temporal information. To address this, they propose Scene-RAG, a retrieval-augmented generation method that improves VLM performance by 2.50% by dynamically integrating relevant context across scenes, highlighting the ongoing challenge in developing robust long-context retention for VLMs. AI
IMPACT Highlights limitations in current VLMs for long-context video understanding, potentially guiding future research towards more robust temporal reasoning capabilities.
