WebFeb 22, 2024 · 5. Use Ensemble learning. Ensemble learning is an approach to improve predictions by training and combining multiple models. What we previously did with K-Fold Cross-Validation was ensemble learning. We trained multiple models and combined the predictions of these models. With K-Fold Cross-Validation, we used the same model … WebK-fold¶ KFold divides all the samples in \(k\) groups of samples, called folds (if \(k = n\), this is equivalent to the Leave One Out strategy), of equal sizes (if possible). The prediction function is learned using \(k - 1\) folds, and the fold left out is used for test. Example of 2-fold cross-validation on a dataset with 4 samples:
