WebMay 4, 2024 · 109 3. Add a comment. -3. I think you will find Optuna good for this, and it will work for whatever model you want. You might try something like this: import optuna def objective (trial): hyper_parameter_value = trial.suggest_uniform ('x', -10, 10) model = GaussianNB (=hyperparameter_value) # … WebThe base AdaBoost classifier used in the inner ensemble. Note that you can set the number of inner learner by passing your own instance. New in version 0.10. When set to True, reuse the solution of the previous call to fit and add more estimators to the ensemble, otherwise, just fit a whole new ensemble. WebDistributions are assumed to implement the optuna distribution interface. cv: Cross-validation strategy. Possible inputs for cv are: - integer to specify the number of folds in a CV splitter, - a CV splitter, - an iterable yielding (train, validation) splits as arrays of indices.
