Stacking (stacked generalization) is a machine learning ensembling technique. Main idea is to use predictions as features. More specifically we predict train set (in CV-like fashion) and test set using some 1st level model(s), and then use these predictions as features for 2nd level model. You can find more details (concept, … See more Often it is also called stacked generalization. The term is derived from the verb to stack(to put together, to put on top of each other). It implies that we put some models on top … See more It depends on specific business case. The main thing to know about stacking is that it requires significant computing resources. No Free Lunch … See more OOF is abbreviation for out-of-fold prediction. It's also known as OOF features, stacked features, stacking features, etc. Basically it means predictions for the … See more I can just do the following. Why not? Code above will give meaningless result. If we fit on X_train we can’t just predict X_train, because our 1st level model has already seen X_train, and its … See more WebJan 22, 2024 · Stacking is a type of ensemble learning wherein multiple layers of models are used for final predictions. More specifically, we predict train set (in CV-like fashion) and test set using some 1st level models, and then use these predictions as features for 2nd level model. We can do it in python using a library called ‘Vecstack’.
