Bayesian optimization has demonstrated impressive success in finding the optimum input and output of the black-box function. In some applications, the optimum output of the function is known in advance and the goal is to find the corresponding optimum input. Existing work in Bayesian optimization (BO) has not effectively exploited the knowledge of the optimum output for optimization. In this paper, we consider a new setting in BO in which the knowledge of the optimum output is available, such as in tuning hyperparameters for deep reinforcement learning and supervised learning. Our goal is to exploit such knowledge to find the optimum input efficiently.
