# E.T. Chat

[arXiv](https://arxiv.org/abs/2409.18111) | [Project Page](https://polyu-chenlab.github.io/etbench) | [GitHub](https://github.com/PolyU-ChenLab/ETBench)

E.T. Chat is a novel time-sensitive Video-LLM that reformulates timestamp prediction as an embedding matching problem, serving as a strong baseline on E.T. Bench. E.T. Chat consists of a visual encoder, a frame compressor, and a LLM. A special token \<vid\> is introduced to trigger frame embedding matching for timestamp prediction.
