Blending classifier
WebHere: Step 1 : Store all the unique output values of the training dataset in a list. Step 2 : For every row in the test dataset, pick up a value from this list randomly. This random output value becomes the prediction of the random pred algo for the corresponding row of the test dataset. That’s it! WebA classifier is an algorithm - the principles that robots use to categorize data. The ultimate product of your classifier's machine learning, on the other hand, is a …

WebMix of strategy A and B, we train the second stage on the (out-of-folds) predictions of the first stage and use the holdout only for a single cross validation of the second stage. Create a holdout of 10% of the train set. Split the train set (without the holdout) in k folds. Fit a first stage model on k-1 folds and predict the kth fold.
