Tree-Structured Parzen Estimator: Understanding Its Algorithm Components and Their Roles for Better Empirical Performance
This paper delves into the Tree-Structured Parzen Estimator (TPE), a popular Bayesian optimization method used in parameter tuning frameworks like Hyperopt and Optuna. The authors aim to clarify the roles of TPE's various control parameters and their influence on tuning performance. Through ablation studies on diverse benchmark datasets, they identify optimal settings that enhance TPE's empirical effectiveness, providing their implementation for use. AI
