Wide Neural Networks Trained with Weight Decay Provably Exhibit Neural Collapse

Arthur Jacot, Peter Súkeník, Zihan Wang +1

Deep neural networks (DNNs) at convergence consistently represent the training data in the last layer via a highly symmetric geometric structure referred to as neural collapse. Thi…

High-dimensional Analysis of Knowledge Distillation: Weak-to-Strong Generalization and Scaling Laws

M. Emrullah Ildiz, Halil Alperen Gozeten, Ege Onur Taga +2

A growing number of machine learning scenarios rely on knowledge distillation where one uses the output of a surrogate model as labels to supervise the training of a target model.…

Information limits and Thouless-Anderson-Palmer equations for spiked matrix models with structured noise

Jean Barbier, Francesco Camilli, Marco Mondelli +1

We consider a prototypical problem of Bayesian inference for a structured spiked model: a low-rank signal is corrupted by additive noise. While both information-theoretic and algor…

Neural Collapse versus Low-rank Bias: Is Deep Neural Collapse Really Optimal?

Peter Súkeník, Marco Mondelli, Christoph Lampert

Deep neural networks (DNNs) exhibit a surprising structure in their final layer known as neural collapse (NC), and a growing body of works has currently investigated the propagatio…

Matrix Denoising with Doubly Heteroscedastic Noise: Fundamental Limits and Optimal Spectral Methods

Yihan Zhang, Marco Mondelli

We study the matrix denoising problem of estimating the singular vectors of a rank- signal corrupted by noise with both column and row correlations. Existing works are either un…
