Gradient descent with early stopping is probably robust to label noise for overparameterized neural networks.

Published on AISTATS 2020

• Demonstrated that large neural networks can overfit to noise, which hurt the accuracy.
• Proved that a large neural network becomes provably robust to label noise when trained with early stopping.

Generalization, Adaptation and Low-Rank Representation in Neural Networks.

Published on Asilomar Conference

• Demonstrated that Jacobian of a neural network exhibit low-rank structure with a few large singular values and many small ones leading to low-dimensional information space.
• Proved that learning on the information space with large singular values is fast and can generalize well but learning on the nuisance space with smaller singular values can impede optimization and generalization.

Exploring Weight Importance and Hessian Bias in Model Pruning

arXiv preprint, in submission

• Counterintuitively, proved that pruning small network weights can provably hurt more than pruning large network weights.
• Established high-dimensional asymptotic bounds in neural networks pruning.
