## Evaluation

Your model will be evaluated using its Root Mean Squared Error (MSE) on the test set. (As usual, you do not have the labels on the test set, of course; so you cannot directly measure the RMSE on it.) You can calculate the MSE on a dataset using scikit-learn https://scikit-learn.org/stable/modules/generated/sklearn.metrics.mean_squared_error.html. Then take the squared root of the MSE to get the RMSE.
