result = cross_val_score(pipeline, X, y, cv=kfold, scoring='accuracy') # report the mean performance print(f'Accuracy: {result.mean():.3f}') Running this example should give you a similar output. 1 Accuracy: 0.760 To learn more about iterative imputation, see the following tutorial:...

To do that, we'll define a small scoring function. def compute_score(clf, X, y, scoring='accuracy'): xval = cross_val_score(clf, X, y, cv = 5, scoring=scoring) return np.mean(xval) Recovering the train set and the test set from the combined dataset is an easy task. def ...
We can use k-fold cross validation support provided in scikit-learn. First we must create the KFold object specifying the number of folds and the size of the dataset. We can then use this scheme with the specific dataset. The cross_val_score() function from scikit-learn allows us to eva...
