Improved model using XGBoost Regressor

[nemishgarg]

I have used XGBoost Regressor and finely tuned it using GridSearchCV. After doing so, there is a great improvement in the model.
New Mean Squared error = 5.767
New R2 score = 0.909

We want less mean square error but your model error is 5.767 which is grater than my model mean square error
