Yiheng Zhang (张怡蘅)
PhD Applicant in Computer Science · University of Wisconsin-Madison, Computer Science
- I am Yiheng Zhang, a senior student at University of Wisconsin-Madison studying computer science, advised by Prof. Grigoris Chrysos. My GPA during the study in University of Wisconsin-Madison was 3.95/4.0.
- My research interests are machine learning and natural language processing, with a focus on large language models (LLMs), diffusion language models (DLLMs), and trustworthy AI. In particular, my projects focused on teaching small arithmetic tasks to transformer, and remasking skills in diffusion language models.
- I am currently applying to Ph.D. programs for Fall 2026 and internships for Summer 2026. Please feel free to contact me if you think I would be a good fit. Thank you.
