About me
I’m Zirui “Ray” Liu, a Ph.D. student from the Department of Computer Science at Rice University, co-advised by Dr. Xia “Ben” Hu and Prof. Vladimir Braverman.
My research interests lie in large-scale machine learning. I develop randomized algorithm and build systems to support them, aiming to scale-up and/or accerlate machine learning models. Some examples include randomized matrix mulplication, randomized matrix sparsification, stochastic quantization.
Recently, I’ve been exploring ways to train, fine-tune, and deploy Large Language Models (LLMs) on commodity hardware, especially making them more accessible to academics.
Email: zl105 at rice dot edu. Here is my CV.
I’m graduating in 2024 and am actively seeking a tenure-track faculty position.
