Asymptotics of feature learning in two-layer networks after one gradient-step

Florent Gérard Krzakala, Lenka Zdeborová, Luca Pesce, Yue Lu, Bruno Loureiro, Hugo Chao Cui

In this manuscript, we investigate the problem of how two-layer neural networks learn features from data, and improve over the kernel regime, after being trained with a single gradient descent step. Leveraging the insight from (Ba et al., 2022), we model t ...

The Benefits of Reusing Batches for Gradient Descent in Two-Layer Networks: Breaking the Curse of Information and Leap Exponents

Florent Gérard Krzakala, Lenka Zdeborová, Emanuele Troiani, Luca Pesce

We investigate the training dynamics of two-layer neural networks when learning multi-index target functions. We focus on multi-pass gradient descent (GD) that reuses the batches multiple times and show that it significantly changes the conclusion about wh ...

Theory and applications of the sum-of-squares technique

Luca Pesce, Elisabetta Cornacchia, Giovanni Piccioli

The sum-of-squares (SOS) approximation method is a technique used in optimization problems to derive lower bounds on the optimal value of an objective function. By representing the objective function as a sum of squares in a feature space, the SOS method t ...
