WebThis early stopping strategy is activated if early_stopping=True; otherwise the stopping criterion only uses the training loss on the entire input data. To better control the early stopping strategy, we can specify a parameter validation_fraction which set the fraction of the input dataset that we keep aside to compute the validation score.
Webn_iter_no_change int, default=None. n_iter_no_change is used to decide if early stopping will be used to terminate training when validation score is not improving.
