Achieve Bayesian optimization for tuning hyper-parameters

WebThe selected hyper-parameter value is the one which achieves the highest average performance across the n-folds. Once you are satisfied with your algorithm, then you can test it on the testing set. If you go straight to the testing set then you are risking overfitting. Share Improve this answer Follow edited Aug 1, 2024 at 18:12 In machine learning, hyperparameter optimization or tuning is the problem of choosing a set of optimal hyperparameters for a learning algorithm. A hyperparameter is a parameter whose value is used to control the learning process. By contrast, the values of other parameters (typically node weights) are learned.
