I wish to try the effect of Data Stream Mining Plugin,
I have tried several combinations including the combination below: Root (Process) +- ExampleSource (ExampleSource) +- DataStreamProvider (DataStreamProvider) +- BayBoostStream (BayBoostStream) +- NaiveBayes (NaiveBayes)
But errors occurs as following: P Sep 15, 2008 6:04:04 PM: [Fatal] NullPointerException occured in 1st application of * DataStreamProvider (DataStreamProvider)
Does anyone successfully apply either of data stream mining operator, such as DataStreamProvider or ConceptDriftSimulator? I will appreaciate very much if you can share the experience with me.
