Core Concepts
Transition from tempered to benign overfitting in ReLU neural networks based on input dimensions and sample sizes.
Abstract
The content discusses the phenomenon of overparameterized neural networks generalizing well even with noisy data, leading to "benign overfitting." It introduces the concept of "tempered overfitting" and explores the transition between tempered and benign overfitting based on input dimensions. Theoretical justifications, empirical observations, and experimental results are provided to shed light on the intricate connections between dimensionality, sample size, architecture, and training algorithms in determining the type of overfitting experienced by neural networks.
