Les Houches Lectures on Deep Learning at Large & Infinite Width

no code implementations4 Sep 2023 Yasaman Bahri, Boris Hanin, Antonin Brossollet, Vittorio Erba, Christian Keup, Rosalba Pacelli, James B. Simon

These lectures, presented at the 2022 Les Houches Summer School on Statistical Physics and Machine Learning, focus on the infinite-width limit and large-width regime of deep neural networks.

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.

Intrinsic dimension estimation for locally undersampled data

1 code implementation18 Jun 2019 Vittorio Erba, Marco Gherardi, Pietro Rotondo

Traditionally, most IDE algorithms are either based on multiscale principal component analysis (PCA) or on the notion of correlation dimension (and more in general on k-nearest-neighbors distances).
