Near-Interpolators: Rapid Norm Growth and the Trade-Off between Interpolation and Generalization
Yutong Wang, Rishi Sonthalia, Wei Hu
We study the generalization capability of nearly-interpolating linear regressors: 's whose training error is positive but small, i.e., below the noise floor. Unde…

Benign Overfitting and Grokking in ReLU Networks for XOR Cluster Data
Zhiwei Xu, Yutong Wang, Spencer Frei +2
Neural networks trained by gradient descent (GD) have exhibited a number of surprising generalization behaviors. First, they can achieve a perfect fit to noisy training data and st…
