Sharp bounds for stochastic proximal and projection estimators via radial dominance

Gonzalo Contador, Pedro Pérez-Aros, Emilio Vilches

We study stochastic barycentric estimators for proximal points and metric projections obtained by exponentially reweighting Gaussian perturbations. Our main result is an abstract c…

Differentiability and Approximation of Probability Functions under Gaussian Mixture Models

Gonzalo Contador, Pedro Pérez-Aros, Emilio Vilches

In this work, we study probability functions associated with Gaussian mixture models. Our primary focus is on extending the use of spherical radial decomposition for multivariate G…
