Hyperparameter tuning via trajectory predictions: Stochastic prox-linear methods in matrix sensing

Mengqi Lou, Kabir Aladin Verchand, Ashwin Pananjady

Motivated by the desire to understand stochastic algorithms for nonconvex optimization that are robust to their hyperparameter choices, we analyze a mini-batched prox-linear iterat…

Computationally efficient reductions between some statistical models

Mengqi Lou, Guy Bresler, Ashwin Pananjady

We study the problem of approximately transforming a sample from a source statistical model to a sample from a target statistical model without knowing the parameters of the source…
