Challenge: Solving Task Using Stacking Regressor
Stacking Regressor is a stacking ensemble learning model used to solve regression tasks. The principle of work of this model is similar to the Stacking Classifier: the only difference is that we use regression algorithms as the base and meta-models of the ensemble.
We can use the StackingRegressor class from the sklearn library to implement this model in Python.

The make_friedman1 dataset is a synthetic dataset frequently used for regression tasks in machine learning. This dataset is widely used in regression tutorials and experimentation because it's simple, yet it can be customized with different noise levels and feature dimensions to simulate various regression scenarios.
Your task is to solve the regression task on the Friedman dataset using Stacking Regressor:
- Provide split on train and test subsets of the training set: the proportion of the dataset to be included in the test split must be
0.2. - Use Decision Tree Regressor with
max_depthequals3as one of the base models. - Create a Stacking Regressor model using base models and meta model.
- Fit Stacking Regressor model on the training data.
