Recent Developments at the Interface Between Kernel Embeddings and Gaussian Processes

Reproducing kernel Hilbert spaces (RKHS) provide a powerful framework, termed kernel mean embeddings, for representing probability distributions, enabling nonparametric statistical inference in a variety of applications. I will give an overview of this framework and present some of its recent developments which combine RKHS formalism with Gaussian process modelling. Some recent applications include causal data fusion, where data of different quality needs to be combined in order to estimate the average treatment effect, as well as statistical downscaling using potentially unmatched multi-resolution data.
