Kernel Identification Through Transformers

1 code implementation NeurIPS 2021 Fergus Simpson, Ian Davies, Vidhi Lalchand, Alessandro Vullo, Nicolas Durrande, Carl Rasmussen

Kernel selection plays a central role in determining the performance of Gaussian Process (GP) models, as the chosen kernel determines both the inductive biases and prior support of functions under the GP prior.

The Minecraft Kernel: Modelling correlated Gaussian Processes in the Fourier domain

no code implementations11 Mar 2021 Fergus Simpson, Alexis Boukouvalas, Vaclav Cadek, Elvijs Sarkans, Nicolas Durrande

In the univariate setting, using the kernel spectral representation is an appealing approach for generating stationary covariance functions.

Gaussian Processes

Marginalised Gaussian Processes with Nested Sampling

1 code implementation NeurIPS 2021 Fergus Simpson, Vidhi Lalchand, Carl Edward Rasmussen

Learning occurs through the optimisation of kernel hyperparameters using the marginal likelihood as the objective.
