             Project: Flink
          Issue Type: Improvement
          Components: Machine Learning Library
            Reporter: Till Rohrmann


Cross validation is a standard tool to select proper parameters for you model and to validate your results. As such it is a crucial tool for every machine learning library.

The cross validation should work with arbitrary learners and ranges of parameters you can specify. A first cross validation strategy it should support is the k-fold cross validation.
