About Me

I am a master's student at Fudan University, advised by Prof. Tao Chen. My research explores how multimodal systems perceive, reason about, and interact with the physical world.

Earlier, I conducted research with Prof. Chang Tang and Assoc. Prof. Bo Zhao. I value work that identifies meaningful new problems, makes difficult problems tractable, and develops approaches that generalize beyond a single benchmark.

Generative Embedding Benchmark Overview

Generative Embedding Benchmark: How Much Information Survives in a Dense Embedding?

Yun Li, Biao Yang, Peixi Wu, Yunhao Zhou, Mingzhou Jiang, Wei Yuan, Fan Yang, Wenwu Ou

arXiv 2026

We introduce the Generative Embedding Benchmark (GEB), which measures how much answer-relevant visual information can be recovered from a frozen embedding through generative readout. Across visual-only and vision-language joint settings, GEB reveals information bottlenecks that separability-based embedding benchmarks do not capture.

STI-Bench Overview

STI-Bench: Are MLLMs Ready for Precise Spatial-Temporal World Understanding?

Yun Li, Yiming Zhang, Tao Lin, XiangRui Liu, Wenxiao Cai, Zheng Liu, Bo Zhao

ICCV 2025

STI-Bench evaluates spatial-temporal understanding in MLLMs through object appearance, pose, displacement, and motion tasks. Built on 300+ videos and 2,000+ QA pairs across diverse scenes, it exposes persistent weaknesses in precise distance estimation and motion analysis.
