SGD at the Edge of Stability: The Stochastic Sharpness Gap
Fangshuo Liao, Afroditi Kolomvaki, Anastasios Kyrillidis
When training neural networks with full-batch gradient descent (GD) and step size , the largest eigenvalue of the Hessian -- the sharpness -- rises to an…

Convergence Analysis of Two-Layer Neural Networks under Gaussian Input Masking
Afroditi Kolomvaki, Fangshuo Liao, Evan Dramko +2
We investigate the convergence guarantee of two-layer neural network training with Gaussian randomly masked inputs. This scenario corresponds to Gaussian dropout at the input level…
