[jira] [Created] (FLINK-2297) Add threshold setting for SVM binary predictions

             Summary: Add threshold setting for SVM binary predictions
                 Key: FLINK-2297
                 URL: https://issues.apache.org/jira/browse/FLINK-2297
             Project: Flink
          Issue Type: Improvement
          Components: Machine Learning Library
            Reporter: Theodore Vasiloudis
            Priority: Minor
             Fix For: 0.10


Currently SVM outputs the raw decision function values when using the predict function.

We should have instead the ability to set a threshold above which examples are labeled as positive (1.0) and below negative (-1.0). Then the prediction function can be directly used for evaluation.
