Parallel Gaussian Process Optimization with Upper Confidence Bound and Pure Exploration

no code implementations19 Apr 2013 Emile Contal, David Buffoni, Alexandre Robicquet, Nicolas Vayatis

We prove theoretical upper bounds on the regret with batches of size K for this procedure which show the improvement of the order of sqrt{K} for fixed iteration cost over purely sequential versions.
