Tree-structured Gaussian Process Approximations
Gaussian process regression can be accelerated by constructing a small pseudodataset to summarize the observed data. This idea sits at the heart of many approximation schemes, but such an approach requires the number of pseudo-datapoints to be scaled with the range of the input space if the accuracy of the approximation is to be maintained. This presents problems in time-series settings or in s...
متن کاملStreaming Sparse Gaussian Process Approximations
Sparse pseudo-point approximations for Gaussian process (GP) models provide a suite of methods that support deployment of GPs in the large data regime and enable analytic intractabilities to be sidestepped. However, the field lacks a principled method to handle streaming data in which both the posterior distribution over function values and the hyperparameter estimates are updated in an online ...
متن کاملGaussian Process Approximations of Stochastic Differential Equations
Stochastic differential equations arise naturally in a range of contexts, from financial to environmental modeling. Current solution methods are limited in their representation of the posterior process in the presence of data. In this work, we present a novel Gaussian process approximation to the posterior measure over paths for a general class of stochastic differential equations in the presen...

subject to q(f |u) = ∏ i q(fi|u) and ∫ dfiq(fi|u) = 1. It is noted that KL(a||b) is the measurement of information “lost” when using b to approximate a. It was argued in [1] that it is appropriate to use this KL divergence as an approximation measure since we are trying to find a sparse representation u and its relationship with f to approximate p by q. The KL divergence above can be expanded a...
متن کاملLocal and global sparse Gaussian process approximations
Gaussian process (GP) models are flexible probabilistic nonparametric models for regression, classification and other tasks. Unfortunately they suffer from computational intractability for large data sets. Over the past decade there have been many different approximations developed to reduce this cost. Most of these can be termed global approximations, in that they try to summarize all the trai...
