Propagation of Chaos in One-hidden-layer Neural Networks beyond Logarithmic Time
Margalit Glasgow, Denny Wu, Joan Bruna
We study the approximation gap between the dynamics of a polynomial-width neural network and its infinite-width counterpart, both trained using projected gradient descent in the me…

Survey on Algorithms for multi-index models
Joan Bruna, Daniel Hsu
We review the literature on algorithms for estimating the index space in a multi-index model. The primary focus is on computationally efficient (polynomial-time) algorithms in Gaus…
