## 📰 News

- **[2024.10.19]** 🔥 We release [trace-retrieval](https://huggingface.co/Yongxin-Guo/trace-retrieval) by forcing the predicted timestamps to be align with the input frame timestamps. Results show trace-retrieval achieve better performance on dense video captioning tasks.
- **[2024.10.10]** 🔥 Our [code](https://github.com/gyxxyg/TRACE) and [paper](https://arxiv.org/abs/2410.05643) are released!
- **[2024.10.10]** 🔥 Our **checkpoints** are available now!

## Overview

In this work
- We model the videos by a series of events, and propose causal event modeling framework to capture videos' inherent structure.
- We present a novel task-interleaved video LLM model, TRACE, tailored to implement the causal event modeling framework through the sequential encoding/decoding of timestamps, salient scores, and textual captions.
