Challenge: Solving Task Using Bagging Regressor

Task

Swipe to show code editor

The load_diabetes dataset contains ten baseline variables (age, sex, BMI, average blood pressure, and six blood serum measurements) for 442 diabetes patients. The target variable is a quantitative measure of disease progression one year after baseline. This dataset is used for predicting the continuous variable, representing diabetes progression, based on the given features.

Your task is to use Bagging Regressor to solve the regression problem on load_diabetes dataset:

Use a simple LinearRegression model as the base model of the ensemble.
Use the BaggingRegressor class to create an ensemble.
Use Mean Squared Error(MSE) to evaluate the results.
