Improved stochastic trace estimation using mutually unbiased bases
J. K. Fitzsimons, M. A. Osborne, S. J. Roberts +1
We examine the problem of estimating the trace of a matrix when given access to an oracle which computes for an input vector . We make use of the basis vecto…
Alternating Optimisation and Quadrature for Robust Control
Supratik Paul, Konstantinos Chatzilygeroudis, Kamil Ciosek +3
Bayesian optimisation has been successfully applied to a variety of reinforcement learning problems. However, the traditional approach for learning optimal policies in simulators d…
Preconditioning Kernel Matrices
Kurt Cutajar, Michael A. Osborne, John P. Cunningham +1
The computational and storage complexity of kernel machines presents the primary barrier to their scaling to large, modern, datasets. A common way to tackle the scalability issue i…
