Title: Bayesian Optimization with Categorical and Continuous

Bayesian optimization (BO) has demonstrated impressive success in optimizing black-box functions. However, there are still challenges in dealing with black-boxes that include both continuous and categorical inputs. I am presenting our recent works in optimizing the mixed space of categorical and continuous variables using Bayesian optimization [1] and how to scale it up to higher dimensions [2] and population-based AutoRL setting [3].
