Linear regression with regularization, with the regularization parameter estimated from cross-validation.

Function y = f(x) = x² + 10 to create a random sample (x_j, y_j) (training data) of size 12 (that is, j = 1 to 12), by uniform random sampling of x in -2 <= x <= 10.

See https://pipenv.readthedocs.io/en/latest/install/#installing-pipenv to install pipenv, if you do not have it.

To run this program:

pipenv run python main.py
