A Novel Stochastic Gradient Descent Algorithm for Learning Principal Subspaces

Charline Le Lan, Joshua Greaves, Jesse Farebrother +4

Many machine learning problems encode their data as a matrix with a possibly very large number of rows and columns. In several applications like neuroscience, image compression or…

Second-order regression models exhibit progressive sharpening to the edge of stability

Atish Agarwala, Fabian Pedregosa, Jeffrey Pennington

Recent studies of gradient descent with large step sizes have shown that there is often a regime with an initial increase in the largest eigenvalue of the loss Hessian (progressive…

Boosting Variational Inference With Locally Adaptive Step-Sizes

Gideon Dresdner, Saurav Shekhar, Fabian Pedregosa +2

Variational Inference makes a trade-off between the capacity of the variational family and the tractability of finding an approximate posterior distribution. Instead, Boosting Vari…

SGD in the Large: Average-case Analysis, Asymptotics, and Stepsize Criticality

Courtney Paquette, Kiwon Lee, Fabian Pedregosa +1

We propose a new framework, inspired by random matrix theory, for analyzing the dynamics of stochastic gradient descent (SGD) when both number of samples and dimensions are large.…

Bridging the Gap Between Adversarial Robustness and Optimization Bias

Fartash Faghri, Sven Gowal, Cristina Vasconcelos +3

We demonstrate that the choice of optimizer, neural network architecture, and regularizer significantly affect the adversarial robustness of linear neural networks, providing guara…

Average-case Acceleration for Bilinear Games and Normal Matrices

Carles Domingo-Enrich, Fabian Pedregosa, Damien Scieur

Advances in generative modeling and adversarial learning have given rise to renewed interest in smooth games. However, the absence of symmetry in the matrix of second derivatives p…
