Changhao He / 何长浩

I am Changhao He (何长浩), a first-year Ph.D. student in the College of Computer Science at Sichuan University, where I am fortunate to be advised by Prof. Peng Hu (胡鹏) and Prof. Xi Peng (彭玺).

I received my Bachelor's degree (2019-2023) from the College of Mechanical Engineering at Sichuan University. After that, I pursued my Master's in the College of Computer Science at Sichuan University and transitioned into the Ph.D. stage through the direct doctoral program (2+4) in 2025. I have been with the XLearning Lab since my Master's studies.

Research

My research focuses on the robustness of multi-modal models during inference. Our group maintains the Awesome Noisy Correspondence repository , a resource hub for research in noisy correspondence. If you have any suggestions or ideas, we warmly invite you to get in touch with us.

Publications (*: equal contribution)

RLSF-V: Mitigating Hallucinations in MLLMs via Fuzzy Semantic Self-Feedback

Changhao He, Shuhao Yan, Shuxian Li, Xi Peng, Peng Hu

ICML, 2026
Paper(Coming soon) /

Code(Coming soon) / Model(Coming soon) / Dataset(Coming soon)

Propose a self-feedback framework for constructing preference data that eliminates the need for external large-model evaluators or human annotations.

Present a novel hallucination assessment method that derives local fuzzy semantics directly from internal logits and seamlessly integrates into a preference optimization pipeline.

DOUBT: Decoupled Object-level Understanding and Bridging via vMF-based Trustworthiness for Hallucination Detection in MLLMs

Kaiqi Chen, Yang Qin, Changhao He, Xi Peng, Peng Hu

ICML, 2026 (Spotlight, Top 2.2%)
Paper(Coming soon) /

Code(Coming soon)

Decouple simple recognition from hard reasoning and guide the model to elicit richer and object-aware responses.

Propose a model-agnostic uncertainty metric based on the vMF distribution to alleviate the instability of traditional entropy measurement.
