-Classical statistical inference relies on numerous tools from probability theory to study
+[[Colloquia/Spring2024|Spring 2024]]
-the properties of estimators. However, these same tools are often inadequate to study
-modern machine problems that frequently involve structured data (e.g networks) or
-complicated dependence structures (e.g dependent random matrices). In this talk, we
-extend universal limit theorems beyond the classical setting.
-Firstly, we consider distributionally “structured” and dependent random object–i.e
+[[Colloquia/Fall 2023|Fall 2023]]
-random objects whose distribution are invariant under the action of an amenable group.
-We show, under mild moment and mixing conditions, a series of universal second and
-third order limit theorems: central-limit theorems, concentration inequalities, Wigner
-semi-circular law and Berry-Esseen bounds. The utility of these will be illustrated by
-a series of examples in machine learning, network and information theory. Secondly
-by building on these results, we establish the asymptotic distribution of the cross-
-validated risk with the number of folds allowed to grow at an arbitrary rate. Using
-this, we study the statistical speed-up of cross validation compared to a train-test split
-procedure, which reveals surprising results even when used on simple estimators.
