    Description

      A score function for Predictor implementations should take a DataSet[(I, O)] and an (optional) scoring measure and return a score.

      The DataSet[(I, O)] would probably be the output of the predict function.

      For example in MultipleLinearRegression, we can call predict on a labeled dataset, get back predictions for each item in the data, and then call score with the resulting dataset as an argument and we should get back a score for the prediction quality, such as the R^2 score.
