[jira] [Assigned] (FLINK-2108) Add score function for Predictors
[ https://issues.apache.org/jira/browse/FLINK-2108?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Theodore Vasiloudis reassigned FLINK-2108: -- Assignee: Theodore Vasiloudis (was: Sachin Goel) 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 Assignee: Theodore Vasiloudis Priority: Minor Labels: ML 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
