Surrogate Model Based Hyperparameter Tuning for Deep Learning with SPOT

05/30/2021 ∙ by Thomas Bartz-Beielstein, et al. ∙ 0

A surrogate model based hyperparameter tuning approach for deep learning is presented. This article demonstrates how the architecture-level parameters (hyperparameters) of deep learning models that were implemented in Keras/tensorflow can be optimized. The implementation of the tuning procedure is 100 few lines of code, existing R packages (tfruns and SPOT) can be combined to perform hyperparameter tuning. An elementary hyperparameter tuning task (neural network and the MNIST data) is used to exemplify this approach.
