Albert Gong

I'm a third-year PhD student in computer science at Cornell, where I'm fortunate to be advised by Raaz Dwivedi and Kilian Q. Weinberger. I'm currently working on using distribution compression (a.k.a. "thinning") to speed up training and inference of large-language models and benchmarking AI agents.

Previously, I was an undergrad at Yale, where I had the privilege of working with Andre Wibisono, Zhong Shao, and Cormac O'Dea.

Low-Rank Thinning
Annabelle Michael Carrell, Albert Gong, Abhishek Shetty, Raaz Dwivedi, Lester Mackey
ICML, 2025
Code (see below) / arXiv

Tl;dr—Developed new analysis of thinning algorithms that adapts to low-rank structures, enabling faster dot-product attention in Transformers (Thinformer), stochastic gradient descent (KH-SGD), and deep kernel hypothesis testing (DeepCTT).
