SUMMARY:Gérard Ben Arous (Courant Institute of Mathematical Sciences\, NYU
 ): Random matrix theory and the high-dimensional optimization dynamics of 
 machine learning
DESCRIPTION:Gérard Ben Arous: I will survey recent progress in the underst
 anding of the optimization dynamics for Machine Learning classical classif
 ication tasks (for the central case of Gaussian mixture models) via the sp
 ectral theory of their Hessian and information or Fisher matrices along th
 e algorithm path. In particular we will see how a classical spectral trans
 ition of Random Matrix Theory plays a major role in this context.\n\nThis 
 relies on joint recent work with Reza Gheissari (Northwestern)\, Jiaoyang 
 Huang (Wharton) and Aukosh Jagannath (Waterloo).
