Importance sampling-based gradient method for dimension reduction in Poisson log-normal model

Bastien Batardière, Julien Chiquet, Joon Kwon +1

High-dimensional count data poses significant challenges for statistical analysis, necessitating effective methods that also preserve explainability. We focus on a low rank constra…

Finite-sum optimization: Adaptivity to smoothness and loopless variance reduction

Bastien Batardière, Joon Kwon

For finite-sum optimization, variance-reduced gradient methods (VR) compute at each iteration the gradient of a single function (or of a mini-batch), and yet achieve faster converg…
