WebbThis is a tool for optimising sklearn-compatible models' hyperparameters. It uses genetic algorithm so, it is much faster than GridSearchCV and gives more consistent results than RandomizedSearchCV. The class GeneticSearchCV is extended of the sklearn's class BaseSearchCV, so it has the same functionality as sklearn's searches. WebbExamples.
