Importance of Tuning Hyperparameters of Machine Learning Algorithms

  title={Importance of Tuning Hyperparameters of Machine Learning Algorithms},
  author={Hilde J. P. Weerts and A. M{\"u}ller and J. Vanschoren},
The performance of many machine learning algorithms depends on their hyperparameter settings. The goal of this study is to determine whether it is important to tune a hyperparameter or whether it can be safely set to a default value. We present a methodology to determine the importance of tuning a hyperparameter based on a non-inferiority test and tuning risk: the performance loss that is incurred when a hyperparameter is not tuned, but set to a default value. Because our methods require the… Expand
