WebAug 25, 2024 · 1. Using Cross validation: Cross validation is a very powerful preventive measure against overfitting, with a clever idea. Create multiple mini train-validation splits within the original train data, and use these to tune your model. We have a standard way of doing so, called the “k-fold cross validation”. Web3.4.1. Validation curve ¶. To validate a model we need a scoring function (see Metrics and scoring: quantifying the quality of predictions ), for example accuracy for classifiers. The proper way of choosing multiple hyperparameters of an estimator is of course grid search or similar methods (see Tuning the hyper-parameters of an estimator ...
