Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for optimizing continuous parameters in online recommendation systems. An example embodiment operates by generating a surrogate model including an updatable statistical model of one or more mappings from candidate configurations of tunable parameters of a target model to values of the objective function. The tunable parameters include a continuous parameter. The embodiment then selects, using an acquisition function and outputs from the surrogate model, candidate configurations of the tunable parameters having the continuous parameter. The embodiment then determines objective-function values that are indicative of performance measures of the target model for the selected candidate. The embodiment then updates the surrogate model.
