A Quick Intro to Leave-One-Out Cross-Validation …

WebLOO cross-validation with python. Posted by Felipe in posts. There is a type of cross-validation procedure called leave one out cross-validation (LOOCV). It is very similar to the more commonly used k − f o l d cross-validation. In fact, LOOCV can be seen as a special case of k − f o l d CV with k = n, where n is the number of data points. WebLOOCV is a special case of k-Fold Cross-Validation where k is equal to the size of data (n). Using k-Fold Cross-Validation over LOOCV is one of the examples of Bias-Variance Trade-off. It reduces the variance shown by LOOCV and introduces some bias by holding out a substantially large validation set. That’s all for this post.

Leave-One-Out Cross-Validation (LOOCV) LOOCV aims to address some of the drawbacks of the validation set approach.
