Problem 2: Demonstrate Overfitting

Problem Description

Write a Python program that trains an unrestricted Decision Tree (no max_depth limit) on the same dataset, and prints both training and test MSE to demonstrate overfitting.

Input

The same dataset as Problem 1.

Output

Training MSE (very low) and test MSE (noticeably higher).

Constraints

• Use the same dataset as Problem 1 for direct comparison.

Example Input

text
(The same dataset as Problem 1)

Example Output

text
Train MSE: 0.001
Test MSE: 0.15

Concepts Covered

DecisionTreeRegressor, overfitting diagnosis.
