Summary: Add score function for Predictors
Key: FLINK-2108
URL: https://issues.apache.org/jira/browse/FLINK-2108
Project: Flink
Issue Type: Improvement
Components: Machine Learning Library
Reporter: Theodore Vasiloudis
Priority: Minor
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.
