R bayesian optimization

WebIn many engineering optimization problems, the number of function evaluations is severely limited by time or cost. These problems pose a special challenge to the field of global optimization, since existing methods often require more function evaluations than can be comfortably afforded. One way to address this challenge is to fit response surfaces to … WebThe search for optimal hyperparameters is called hyperparameter optimization, i.e. the search for the hyperparameter combination for which the trained model shows the best performance for the given data set. Popular methods are Grid Search, Random Search and Bayesian Optimization. This article explains the differences between these approaches ...
