Computational Thresholds in Multi-Modal Learning via the Spiked Matrix-Tensor Model

Hugo Tabanelli, Pierre Mergny, Lenka Zdeborova +1

We study the recovery of multiple high-dimensional signals from two noisy, correlated modalities: a spiked matrix and a spiked tensor sharing a common low-rank structure. This sett…

Asymptotics of SGD in Sequence-Single Index Models and Single-Layer Attention Networks

Luca Arnaboldi, Bruno Loureiro, Ludovic Stephan +2

We study the dynamics of stochastic gradient descent (SGD) for a class of sequence models termed Sequence Single-Index (SSI) models, where the target depends on a single direction…

Statistical physics analysis of graph neural networks: Approaching optimality in the contextual stochastic block model

O. Duranthon, L. Zdeborová

Graph neural networks (GNNs) are designed to process data associated with graphs. They are finding an increasing range of applications; however, as with other modern machine learni…

On the Atypical Solutions of the Symmetric Binary Perceptron

Damien Barbier, Ahmed El Alaoui, Florent Krzakala +1

We study the random binary symmetric perceptron problem, focusing on the behavior of rare high-margin solutions. While most solutions are isolated, we demonstrate that these rare s…

Compressed sensing with l0-norm: statistical physics analysis and algorithms for signal recovery

D. Barbier, C Lucibello, L. Saglietti +2

Noiseless compressive sensing is a protocol that enables undersampling and later recovery of a signal without loss of information. This compression is possible because the signal i…

Bayes-optimal inference for spreading processes on random networks

D. Ghio, A. L. M. Aragon, I. Biazzo +1

We consider a class of spreading processes on networks, which generalize commonly used epidemic models such as the SIR model or the SIS model with a bounded number of re-infections…
