Way to get list of the actual "nearest neighbors"?

keith

When applying a NearestNeighbor model, is there a way to return the list nearest neighbor points for each predicted value?

In other words, if I run an existing KNN model to predict new values on 100 new examples, where K=5, I want to return the five nearest neighbor point matches for each example.  Something like


Example#  Neighbor    ID
1              1                AAA
1              2                BBB
1              3                CCC
1              4                DDD
1              5                EEE
2              1                FFF
2                2                CCC
2                3                GGG
2                4                AAA
2                5                HHH
3                1                JJJ
etc.


Even if it doesn't rank the neighbors, just getting a list of neighbors for each example row would be great.  Any suggestions are appreciated.

Hi Keith,

I do not know if this is possible with RapidMiner without checking, but I assume that it is at least not a one-operator-process ..

However, I would start by using the [tt]ExampleSet2SimilarityExampleSet[/tt] operator in combination with some filtering techniques ... did you try that already?
