Sparse Gaussian Processes With Spherical Harmonic Features Revisited We compare the approximation to the full gaussian process, sparse spectrum gp, sparse pseudo input gp, and random projections. we show that alternative approximations ei ther over fit or under fit even on simple datasets. This paper develops a new principled framework for de ploying gaussian process probabilistic models in the streaming setting, providing methods for learning hyperparameters and optimising pseudo input locations. the proposed framework is assessed using synthetic and real world datasets. We propose a new sparse posterior approximation framework using power expectation propagation (power ep), unifying various existing methods into one single computational and algorithmic. Standard sparse pseudo input approximations to the gaussian process (gp) cannot handle complex functions well. sparse spectrum alternatives attempt to answer this but are known to over fit. we suggest the use of variational inference for the sparse spectrum approximation to avoid both issues.

Gaussian process models require approximations in order to be practically useful. this thesis focuses on understanding existing approximations and investigating new ones tailored to specific applications. Many of these schemes employ a small set of pseudo data points to summarise the actual data. in this paper we develop a new pseudo point approximation framework using power expectation propagation (power ep) that unifies a large number of these pseudo point approximations.
