Hitting the High-Dimensional Notes: An ODE for SGD learning dynamics on GLMs and multi-index models

no code implementations17 Aug 2023 Elizabeth Collins-Woodfin, Courtney Paquette, Elliot Paquette, Inbar Seroussi

In addition to the deterministic equivalent, we introduce an SDE with a simplified diffusion coefficient (homogenized SGD) which allows us to analyze the dynamics of general statistics of SGD iterates.

Overlap of a spherical spin glass model with microscopic external field

no code implementations19 Jan 2021 Elizabeth Collins-Woodfin

Previous research has noted that, at low temperature, this overlap exhibits dramatically different behavior in the presence of an external field as compared to the model with no external field.
