Albert Gong I'm a second-year PhD student in Computer Science at Cornell, where I'm fortunate to be advised by Raaz Dwivedi and Kilian Q. Weinberger. My current work uses thinning to speed up training and inference of machine learning methods, from kernel methods to large-language models. I'm also interested in applying these techniques to improve LLM agents. Previously, I was an undergrad at Yale, where I had the privilege of working with Andre Wibisono, Zhong Shao, and Cormac O'Dea.
