This operator clusters a set of tuples.
This example uses the weka-clusterer. The weka-clusterer should use the "simplekmeans" algorithm. the arguments to set up the weka-simplekmeans is "-N 3".
clustered = CLUSTERING({ attributes=['age', 'income'], clusterer='weka', algorithm = [ 'model'='SimplekMeans' , 'arguments'='-N 3' ] }, inputoperator) |
For weka, there are currently the following algorithms that can be used as the "model". Further details and possible arguments can beĀ found in the Weka Docs
