Web24 de mar. de 2024 · In this tutorial, we’ll talk about two cross-validation techniques in machine learning: the k-fold and leave-one-out methods. To do so, we’ll start with the train-test splits and explain why we need cross-validation in the first place. Then, we’ll describe the two cross-validation techniques and compare them to illustrate their pros and cons.

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.
