Hello, I am Keyan Zhou(ε¨ζ―θ¨), a PhD student at Fudan University and Shanghai Innovation Institute, under the supervision of Prof. Ziwei He and Prof. Xipeng Qiu.
My research focuses on long-context modeling, with an emphasis on improving how language models learn from and utilize long-form contexts. Specifically, I explore effective data strategies for long-context pre-training and develop post-training methods to enhance modelsβ retrieval and reasoning capabilities in long-context scenarios.

MMLongCite: A Benchmark for Evaluating Fidelity of Long-Context Vision-Language Models
Keyan Zhou, Zecheng Tang, Lingfeng Ming, Guanghao Zhou, Qiguang Chen, Dan Qiao, Zheming Yang, Libo Qin, Minghui Qiu, Juntao Li, Min Zhang
- This work rigorously evaluates multimodal modelsβ ability to utilize information in long-context settings through citation generation tasks and is a comprehensive multimodal benchmark covering images, videos, and documents. The findings highlight a significant gap between the correctness of their responses and their faithful citation of the context.

L-CiteEval: A Suite for Evaluating Fidelity of Long-context Models
Zecheng Tang*, Keyan Zhou*, Juntao Li, Baibei Ji, Jianye Hou, Min Zhang
- This work proposes a long-context benchmark L-CiteEval, which evaluates the citation quality of LCMs and highlights the tendency of current open-source LCMs to rely on intrinsic knowledge rather than the provided context for generating responses.

CMD: a framework for Context-aware Model self-Detoxification
Zecheng Tang*, Keyan Zhou*, Juntao Li, Yuyang Ding, Pinzheng Wang, Yan Bowen, Renjie Hua, Min Zhang
- This work proposes a context-aware detoxification framework, balancing detoxification and generation quality.

Revealing and Mitigating Over-attention in Knowledge Editing
Pinzheng Wang, Zecheng Tang, Keyan Zhou, Juntao Li, Qiaoming Zhu, Min Zhang
- This work reveals the over-attention issue in knowledge eiditing.

LOOM-Scope: a comprehensive and efficient LOng-cOntext Model evaluation framework
Zecheng Tang, Haitian Wang, Quantong Qiu, Baibei Ji, Ruoxi Sun, Keyan Zhou, Juntao Li, Min Zhang
- This work standardizes long-context evaluation across 22 benchmarks, integrates inference acceleration techniques, and introduces a lightweight comprehensive long-context benchmark called LOOMBench.
