Webb22 okt. 2024 · Once the model training start, keep patience as Grid search is computationally expensive and takes time to complete. Once the training is over, you can access the best hyperparameters using the .best_params_ attribute. Here, we can see that with a max depth of 4 and 300 trees we could achieve a good model. WebbThere is two Approaches to look for the best parameters : 1) GridSearchCV : We try every combination of a present list of values of the hyper-parameters and choose the best combination based on the cross validation score.-It takes a lot of time to fit (because it will try all the combinations) + gives us the best hyper-parameters. exemple ;

In contrast to grid search, not all parameter values are tried out, but rather a fixed number of parameter settings is sampled from the specified distributions. The number of parameter settings that are tried is specified in the n_iter parameter.
