COMS 4771: Homework 2 Question 4： Understanding model complexity and overfitting Steven Liu (xl2948) First put digits.mat in the current directory. Then, either enter "python main.py" on Terminal or use PyCharm to run. You can change K (max depth of the tree) and rate_of_training (percentage of training data in the dataset) in the main function (Line 192-193). Sample output: /Users/stevenliu/PycharmProjects/ml-hw2/venv/bin/python /Users/stevenliu/PycharmProjects/ml-hw2/main.py ============================================================ Loading data... ============================================================ Splitting data... ============================================================ Total data: 10000 train_num: 8000 test_num: 2000 ============================================================ Benchmarking... Training Error: 0.01925 ============================================================ Benchmarking... Testing Error: 0.173 Process finished with exit code 0
