Hyperparameter Tuning and Optimization Applications

This chapter reflects on advantages and sense of use of Hyperparameter Tuning (HPT) and its disadvantages. In particular it shows how important it is, to keep the human in the loop, even if HPT works perfectly. The chapter presents a collection of HPT studies. First, HPT applications in Machine Learning (ML) and Deep Learning (DL) are described. A special focus lies on automated ML, neural architecture search, and combined approaches. HPT software is presented. Finally, model based approaches, especially applications with Sequential Parameter Optimization Toolbox (SPOT) are discussed.
