bookChallenge: Solving Task Using AdaBoost Regressor

AdaBoost Regressor is an ensemble learning algorithm used for regression tasks.

The principle of work of such a regressor coincides with the principle of work of the AdaBoost Classifier. The only difference is that we use some regression algorithms (linear regression, decision tree regressor, polynomial regression, etc.) as a base model.

The AdaBoostRegressor class in Python provides tools to train the model and make predictions.

Task

Your task is to create a model to solve the regression task on the diabetes dataset:

  1. Use a simple Linear Regression model as the base model of an ensemble.
  2. Create an AdaBoost Regressor model with the 50 base estimators.
  3. Print MSE to estimate regression quality.
