[인공지능 논문 Review - 07] Bayesian Optimisation over Multiple Continuous and Categorical Inputs

[Bayesian Optimisation over Multiple Continuous and Categorical Inputs]

(B. Ru et al., ICML-2020)


Multi-armed bandits and Bayesian optimization are closely related problems.


In general, Bayesian optimization can be seen as an infinite-bandit extension with dependent arms. While Bayesian optimization with Gaussian process surrogate models assume real-valued inputs, we often face problems where both continuous and categorical inputs exist together.


This paper proposes a new approach, Continuous and Categorical Bayesian Optimization (CoCaBO), which combines the strengths of multi-armed bandits and Bayesian optimization to select values for both categorical and continuous inputs. It models this mixed-type space using a Gaussian process kernel, designed to allow sharing of information across multiple categorical variables, each with multiple possible values; this allows CoCaBO to leverage all available data efficiently. It is empirically demonstrated that the method outperforms existing approaches on both synthetic and real-world problems.
