Error bounds for any regression model using Gaussian processes with gradient information

AISTATS 2024poster

We provide an upper bound for the expected quadratic loss on new data for any regression model. We derive the bound by modelling the underlying function by a Gaussian process (GP). Instead of a single kernel or family of kernels of the same form, we consider all GPs with translation-invariant and co…

Non-geodesically-convex optimization in the Wasserstein space

NeurIPS 2024poster

We study a class of optimization problems in the Wasserstein space (the space of probability measures) where the objective function is nonconvex along generalized geodesics. Specifically, the objective exhibits some difference-of-convex structure along these geodesics. The setting also encompasses s…
