Definition

Leave-one-out cross-validation is a special case of  cross-validation where the number of folds equals the number of  instances in the  data set. Thus, the learning algorithm is applied once for each instance, using all other instances as a  training set and using the selected instance as a single-item  test set. This process is closely related to the statistical method of jack-knife estimation (Efron 1982).
