Compression of Structured Data with Autoencoders: Provable Benefit of Nonlinearities and Depth

ICML 2024poster

Autoencoders are a prominent model in many empirical branches of machine learning and lossy data compression. However, basic theoretical questions remain unanswered even in a shallow two-layer setting. In particular, to what degree does a shallow autoencoder capture the structure of the underlying d…

Fundamental Limits of Two-layer Autoencoders, and Achieving Them with Gradient Methods

ICML 2023oral

Autoencoders are a popular model in many branches of machine learning and lossy data compression. However, their fundamental limits, the performance of gradient methods and the features learnt during optimization remain poorly understood, even in the two-layer setting. In fact, earlier work has cons…

Estimation in Rotationally Invariant Generalized Linear Models via Approximate Message Passing

ICML 2022spotlight

We consider the problem of signal estimation in generalized linear models defined via rotationally invariant design matrices. Since these matrices can have an arbitrary spectral distribution, this model is well suited for capturing complex correlation structures which often arise in applications. We…
