Motivated by various practical applications, we propose a novel and general formulation of
targeted multi-objective hyperparameter optimization. Our formulation allows a clear
specification of an automatable optimization goal using lexicographic preference over
multiple objectives. We then propose a randomized directed search method named
LexiFlow to solve this problem. We demonstrate the strong empirical performance of the
proposed algorithm in multiple hyperparameter optimization tasks.
