Comparison between grid search and successive halving

WebThe design of Surprise’s cross-validation tools is heavily inspired from the excellent scikit-learn API. A special case of cross-validation is when the folds are already predefined by some files. For instance, the movielens-100K dataset already provides 5 train and test files (u1.base, u1.test … u5.base, u5.test). WebThis example compares the parameter search performed by HalvingGridSearchCV and GridSearchCV. We first define the parameter space for an SVC estimator, and compute the time required to train a HalvingGridSearchCV instance, as well as a GridSearchCV instance. We now plot heatmaps for both search estimators.
