Self-regularization and structural adaptation of NPMLE for Gaussian mixture models in all dimensions

The proof applies a multivariate Jensen-type bound to control the typical number of critical points of the KKT function associated with the first-order optimality conditions, to lower bound its gradient norm uniformly on complex spheres.

Empirical Bayes linear regression in high dimensions: Method of moments and sub-linear sample complexity

Under mild design conditions, satisfied by a broad class of correlated random designs, it is shown that EBMoM consistently estimates a growing number of moments and hence the prior itself, provided that $n\geq p^{1-o(1)}$.
