http://nanjiang.cs.illinois.edu/files/cv-nanjiang.pdf WebStacking is an ensemble learning technique to combine multiple regression models via a meta-regressor. The StackingCVRegressor extends the standard stacking algorithm (implemented as StackingRegressor) using out-of-fold predictions to prepare the input data for the level-2 regressor. In the standard stacking procedure, the first-level ...
