Noam Razin

Computer Science PhD Candidate

Tel Aviv University

I’m a PhD candidate in the School of Computer Science at Tel Aviv University, fortunate to be advised by Nadav Cohen.

My research interests broadly include the theoretical foundations and applications of machine learning. More specifically, I focus on mathematically analyzing aspects of deep learning (such as expressiveness, optimization, and generalization), with the goal of establishing theoretically backed practices.

My research is generously supported by the Apple Scholars in AI/ML and the Tel Aviv University Center for AI & Data Science PhD fellowships.
