5 Automating hyperparameter optimization

This chapter covers

Developing a process to manually optimize hyperparameters for DL networks
Building automatic hyperparameter optimization with random search
Formalizing automatic HPO by employing a grid search algorithm
Applying evolutionary computation to HPO using PSO
Extending evolutionary HPO by using evolutionary strategies
Applying DE to HPO

In the past few chapters, we have been exploring various forms of evolutionary computation, from genetic algorithms to particle swarm optimization and even advanced methods like evolutionary strategies and differential evolution. We continue to use all these EC methods through the rest of the book in some capacity to improve on DL. We combine these methods ...
