For a polynomial regression method, if you increase the degree of the polynomial from p=3 to p=5, then the training error and test error both decreases. It indicates the model with p=3 suffers from A. Underfitting B. Overfitting C. Neither A or B For a polynomial regression method, if you increase the degree of the polynomial, the training error decreases but the test error increases. As you increase the degree, what is happening to the model? A. Underfitting B. Overfitting C. Neither A or B
