Supervised Learning III Classification, Regularization Detecting overfitting Plot model complexity versus objective function on test/train data As model becomes more complex, performance on training keeps improving while on test data it increases Horizontal axis: measure of model complexity In this example, we use the maximum order of the polynomial basis functions. Vertical axis: For regression,
