On Learning Gaussian Multi-index Models with Gradient Flow
Alberto Bietti, Joan Bruna, Loucas Pillaud-Vivien
We study gradient flow on the multi-index regression problem for high-dimensional Gaussian data. Multi-index functions consist of a composition of an unknown low-rank linear projec…
Conditionally Strongly Log-Concave Generative Models
Florentin Guth, Etienne Lempereur, Joan Bruna +1
There is a growing gap between the impressive results of deep image generative models and classical algorithms that offer theoretical guarantees. The former suffer from mode collap…
Voice Conversion using Convolutional Neural Networks
Shariq Mobin, Joan Bruna
The human auditory system is able to distinguish the vocal source of thousands of speakers, yet not much is known about what features the auditory system uses to do this. Fourier T…
