Xinyuan Cheng

I am a Master’s student in Computational Linguistics and Informatics at the Center for Information and Language Processing (CIS) at Ludwig-Maximilians-Universität München (LMU Munich). My work focuses on evaluating and interpreting foundation model behavior beyond single accuracy numbers.

My research interests include large language models, reasoning, retrieval-augmented generation (RAG), multilingual and pragmatic evaluation, and human label variation (HLV).

Before that, I received my Bachelor’s degree from Shanghai Jiao Tong University (SJTU).

Currently, I am also a Scientific Programmer at Munich AI & NLP (MaiNLP), where I am developing an open-source, research-oriented toolkit for HLV.
