Nonasymptotic theory for two-layer neural networks: Beyond the bias–variance trade-off
Manuscript, 2023
This paper gives a unified statistical guarantee for both underparametrized and overparametrized two-layer ReLU networks, and further reproduces the double descent phenonmenon. Full paper available for download.
