WebProcess Upper Conﬁdence Bound (MF-GP-UCB) for this setting. 2. Our theoretical analysis proves that MF-GP-UCB explores the space at lower ﬁdelities and uses the high ﬁdelities in successively smaller regions to zero in on the optimum. As lower ﬁdelity queries are cheaper, MF-GP-UCB has better regret than single ﬁdelity strategies. 3.
