On the Geometry of Regularization in Adversarial Training: High-Dimensional Asymptotics and Generalization Bounds

no code implementations21 Oct 2024 Matteo Vilucchio, Nikolaos Tsilivis, Bruno Loureiro, Julia Kempe

Indeed, controlling the complexity of the model class is particularly important when data is scarce, noisy or contaminated, as it translates a statistical belief on the underlying structure of the data.

Binary Classification Generalization Bounds

A High Dimensional Statistical Model for Adversarial Training: Geometry and Trade-Offs

no code implementations8 Feb 2024 Kasimir Tanner, Matteo Vilucchio, Bruno Loureiro, Florent Krzakala

This work investigates adversarial training in the context of margin-based linear classifiers in the high-dimensional regime where the dimension $d$ and the number of data points $n$ diverge with a fixed ratio $\alpha = n / d$.

Adversarial Robustness

Asymptotic Characterisation of Robust Empirical Risk Minimisation Performance in the Presence of Outliers

1 code implementation30 May 2023 Matteo Vilucchio, Emanuele Troiani, Vittorio Erba, Florent Krzakala

We study robust linear regression in high-dimension, when both the dimension $d$ and the number of data points $n$ diverge with a fixed ratio $\alpha=n/d$, and study a data model that includes outliers.

Genealogical Population-Based Training for Hyperparameter Optimization

1 code implementation30 Sep 2021 Antoine Scardigli, Paul Fournier, Matteo Vilucchio, David Naccache

HyperParameter Optimization (HPO) aims at finding the best HyperParameters (HPs) of learning models, such as neural networks, in the fastest and most efficient way possible.
