3 Training vs. Test Error

For the questions below, assume that error means RMS (root mean squared error).

1. Suppose we perform unregularized regression on a dataset. Is the validation error always higher than the training error? Explain.

2. Suppose we perform unregularized regression on a dataset. Is the training error with a degree 10 polynomial always lower than or equal to that using a degree 9 polynomial? Explain

. 3. Suppose we perform both regularized and unregularized regression on a dataset. Is the testing error with a degree 20 polynomial always lower using regularized regression compared to unregularized regression? Explain.
