Arguments
numAtts
the number of dimensions of the data stream.
numCluster
the average number of clusters at any point in time.
numClusterRange
amount by which the actual number of clusters can
deviate from numCluster.
avgSubspaceSize
the average number of dimensions in the subspace of a
cluster.
avgSubspaceSizeRange
the amount by which the number of dimensions can
deviate from avgSubspaceSize.
kernelRadii
the average radii of the clusters in the model.
kernelRadiiRange
the amount by which the radii can deviate from
kernelRadii.
numOverlappedCluster
the number of overlapped clusters at the beginning
of the stream.
overlappingDegree
how close the initially overlapped clusters are
densityRange
how strongly the amount of points in each cluster differs
from each other. 0 means all clusters have the same size. 1 is the maximum
value.
noiseLevel
amount of noise
noiseInCluster
can noise be placed in a cluster?
speed
every speed points, the clusters move by 0.01
speedRange
speed/Velocity point offset
eventFrequency
events happen every eventFrequency points if at least one event is enabled and numClusterRange is set
eventMergeSplit
can clusters merge or split?
eventDeleteCreate
can clusters be deleted or created?
subspaceEventFrequency
Subspace event frequency by each cluster movement destination.
decayHorizon
decay horizon
decayThreshold
decay horizon threshold
modelRandomSeed
number used to seed the RNG for the model
instanceRandomSeed
number used to seed the RNG for the instances
