@inproceedings{Wu2021HierarchicalIP, title={Hierarchical Inducing Point Gaussian Process for Inter-domain Observations}, author={Luhuan Wu and Andrew Miller and Lauren Anderson and Geoff Pleiss and David M. Blei and John P. Cunningham}, booktitle={AISTATS}, year={2021} }

We examine the general problem of interdomain Gaussian Processes (GPs): problems where the GP realization and the noisy observations of that realization lie on different domains. When the mapping between those domains is linear, such as integration or differentiation, inference is still closed form. However, many of the scaling and approximation techniques that our community has developed do not apply to this setting. In this work, we introduce the hierarchical inducing point GP (HIP-GP), a…
