>          Components: ml
>    Affects Versions: 2.12
>            Reporter: Leo Vuylsteker
>            Priority: Blocker

> It seems to me that the KNNRegressionWeightedPredictor.predict implementation is incorrect. Indeed, the weighting term 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.
