----------------------------------

             Summary: KNN(k nearest neighbor) algorithm
                 Key: IGNITE-6880
                 URL: https://issues.apache.org/jira/browse/IGNITE-6880
             Project: Ignite
          Issue Type: New Feature
      Security Level: Public (Viewable by anyone)
          Components: ml
            Reporter: Yury Babak


We want to add KNN to Apache Ignite ML module.

Our implementation should support two modes:

* KNN-classifier(in this mode the output is a class membership. An object is classified by a majority vote of its neighbors, with the object being assigned to the class most common among its k nearest neighbors (k is a positive integer, typically small). If k = 1, then the object is simply assigned to the class of that single nearest neighbor)
* KNN-regression(the output is the property value for the object. This value is the average of the values of its k nearest neighbors.)
