Minimax learning rates for estimating binary classifiers under margin conditions
Jonathan García, Philipp Petersen
We study classification problems using binary estimators where the decision boundary is described by horizon functions and where the data distribution satisfies a geometric margin…

High-dimensional classification problems with Barron regular boundaries under margin conditions
Jonathan García, Philipp Petersen
We prove that a classifier with a Barron-regular decision boundary can be approximated with a rate of high polynomial degree by ReLU neural networks with three hidden layers when a…
