Three Facets of Understanding Pre-training: Loss, Inductive Bias, and Implicit Bias
AI is undergoing a paradigm shift with the rise of models pre-trained with self-supervisions and then adapted to a wide range of downstream tasks. However, their working largely remains a mystery; cla...

Large-N theory of critical Fermi surface and strange metal
We describe the large N saddle point, and the structure of fluctuations about the saddle point, of a theory containing a sharp, critical Fermi surface in twospatial dimensions. The theory describes th...
