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=['source'], learner='weka', algorithm ='SimpleKMeans', options = [ ['arguments','-N 3 -I 500 -S 10 -O']] }, input) |
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
