Spherical Inducing Features for Orthogonally-Decoupled Gaussian Processes

ICML 2023oral

Despite their many desirable properties, Gaussian processes (GPs) are often compared unfavorably to deep neural networks (NNs) for lacking the ability to learn representations. Recent efforts to bridge the gap between GPs and deep NNs have yielded a new class of inter-domain variational GPs in which…

Batch Bayesian optimisation via density-ratio estimation with guarantees

NeurIPS 2022accept

Bayesian optimisation (BO) algorithms have shown remarkable success in applications involving expensive black-box functions. Traditionally BO has been set as a sequential decision-making process which estimates the utility of query points via an acquisition function and a prior over functions, such…

BORE: Bayesian Optimization by Density-Ratio Estimation

ICML 2021oral

Bayesian optimization (BO) is among the most effective and widely-used blackbox optimization methods. BO proposes solutions according to an explore-exploit trade-off criterion encoded in an acquisition function, many of which are computed from the posterior predictive of a probabilistic surrogate mo…
