[SOLVED] KMeans and Nominal Measures
Hi,
I am new in the forum and I have a question about kMeans.
I have read in the forum that it is not possible to use polynominal data for kMeans algorithm. But in RapidMiner 5.2.008, it is possible to choose nominal measures (e.g. nominal distance) and to determine clusters with centroids of polynominal data. There is only a warning that it is not possible to use polynominal data by kMeans, but it is possible because I get "good" results.
How does RapidMiner calculate the clusters? Is it possible to have a look on the different steps during the calculation?
Greetings,
Anne
