Leo Vuylsteker updated IGNITE-16606:
------------------------------------
Description:
It seems to me that the KNNRegressionWeightedPredictor.predict implementation
is incorrect. Indeed, the weighting term (for both sum and div variables)
currently used is distance but it should be 1 / distance if I am not mistaken.
I believe that it could be a major issue that you might want to modify quickly.
