Benign Overfitting in Two-Layer ReLU Convolutional Neural Networks for XOR Data

no code implementations3 Oct 2023 Xuran Meng, Difan Zou, Yuan Cao

Modern deep learning models are usually highly over-parameterized so that they can overfit the training data.

Per-Example Gradient Regularization Improves Learning Signals from Noisy Data

no code implementations31 Mar 2023 Xuran Meng, Yuan Cao, Difan Zou

In this paper, we explore the per-example gradient regularization (PEGR) and present a theoretical analysis that demonstrates its effectiveness in improving both test error and robustness against noise perturbations.

Multiple Descent in the Multiple Random Feature Model

no code implementations21 Aug 2022 Xuran Meng, Jianfeng Yao, Yuan Cao

Recent works have demonstrated a double descent phenomenon in over-parameterized learning.

Impact of classification difficulty on the weight matrices spectra in Deep Learning and application to early-stopping

no code implementations26 Nov 2021 Xuran Meng, Jianfeng Yao

A main contribution from the paper is that we identify the difficulty of the classification problem as a driving factor for the appearance of heavy tail in weight matrices spectra.
