The new Get Local Interpretation Operator...
I have been experimenting with the Get Local Interpretation operator introduced in 7.6 that is included in the RapidMiner extension "Operator Toolbox" under the "Models" sub-folder. I have tried using this operator with a grouped model (normalisation and kNN model) and get an error. The error (screen shot attached) states that I am passing the wrong type of input to the operator.
With a kNN, I have heard that it is best to normalize the input data, and then group the normalization model with the kNN model using the Group Models operator. The error message seems to indicate that the Get Local Interpretation operator cannot accept Grouped Models as an input.
I would be grateful for any advise as to how to get around this if at all possible given the usefullness of the Get Local Interpretation operator, and given that it is sometimes neccessary to normalize the input data that will be processed by a learner.
Best wishes, Michael Martin
