Previous:Cross Validation to Avoid Overfitting in Machine Learning Next:Unsupervised Learning Models

In this post, we will provide an example of Cross Validation using the K-Fold method with the python scikit learn library. The K-Fold Cross Validation example would have k parameters equal to 5. By using a ‘for’ loop, we will fit each model using 4 folds for training data and 1 fold for testing data, and then we will call the accuracy_score method from scikit learn to determine the accuracy of the model.
