Consider a linear regression model on a dataset which we split into a training set and a test set. After training, our model gives a mean-squared error of 0.1 on the training set and a mean-squared error of 5.3 on the test set. Recall that the mean-squared error (MSE) is given by:
$$MSE_{ extbf{w}}( extbf{y}, extbf{X}) = rac{1}{2N} \sum_{n=1}^N (y_n - extbf{x}_n^ op extbf{w})^2$$
Which of the following statements is extbf{correct} ?
A. Retraining the model with feature augmentation (e.g. adding polynomial features) will increase the training MSE.
B. Using cross-validation can help decrease the training MSE of this very model.
C. Retraining while discarding some training samples will likely reduce the gap between the train MSE and the test MSE.
