That means that N separate times, the function approximator is trained on all the data except for one point and a prediction is made for that point. Leave-One-Out cross-validator Provides train/test indices to split data in train/test sets. Each sample is used once as a test set (singleton) while the remaining samples form the training set. Note: LeaveOneOut () is equivalent to KFold (n_splits=n) and LeavePOut (p=1) where n is the number of samples. Leave-one-out cross-validation is an extreme case of k-fold cross-validation, in which we perform N validation iterations. At each i iteration, we train the model with all but the i^{th} data point, and the test set consists only of the i^{th} data point.

At each i iteration, we train the model with all but the i^{th} data point, and the test set consists only of the i^{th} data point. Leave-One-Out Cross-Validation (LOOCV) LOOCV is the case of Cross-Validation where just a single observation is held out for validation. Leave-one-out Cross Validation g Leave-one-out is the degenerate case of K-Fold Cross Validation, where K is chosen as the total number of examples n For a dataset with N examples, perform N experiments n For each experiment use N-1 examples for training and the remaining example for testing I like to use Leave-One-Out Cross-Validation in mlr3 (as part of a pipeline). I could specify the number of folds (=number of instances) e.g.
