Using the regression tree algorithm for the regressors challenge

In this section, we will see how a regression tree algorithm can be used for the regressors challenge:

1. First, we train the model using a regression tree algorithm:

2. Once the regression tree model is trained, we use the trained model to predict the values:

y_pred = regressor.predict(X_test)

3. Then, we calculate RMSE to quantify the performance of the model:

from sklearn.metrics import mean_squared_errorfrom math import sqrtsqrt(mean_squared_error(y_test, y_pred))

We get the following output:
