VideoBrain: Learning Adaptive Frame Sampling for Long Video Understanding

ICML 2026poster

Long-form video understanding remains challenging for Vision-Language Models (VLMs) due to the inherent tension between computational constraints and the need to capture information distributed across thousands of frames. Existing approaches either sample frames uniformly (risking information loss) …

BadAgent: Inserting and Activating Backdoor Attacks in LLM Agents

ACL 2024long

With the prosperity of large language models (LLMs), powerful LLM-based intelligent agents have been developed to provide customized services with a set of user-defined tools. State-of-the-art methods for constructing LLM agents adopt trained LLMs and further fine-tune them on data for the agent tas…
