NettetLeave-one-out cross-validation (LOOCV) is closely related to the validation set approach as it involves splitting the set of observations into two parts. However, instead of creating two subsets of comparable size (i.e. 60% training, 40% validation), a single observation ( ) is used for the validation set, and the remaining observations { } make up the training set. Nettetout. Section 3 proposes a simple model selection procedure for KLR based on an efficient, closed-form approximation of the leave-one-out and k-fold cross-validation estimates of the test cross-entropy. Section 4 compares model selection procedures based on approximate leave-one-out and conventional k-fold cross-validation. Results …

Nettet17. jan. 2024 · The leave-one-out procedure is highly costly and may be unfeasible on many applications; When we have a regression with the number of dimensions approximating the number of instances, this method loses coverage.
