Help requested to apply Data Stream Mining Plugin
Contributor I
I wish to try the effect of Data Stream Mining Plugin,
I have tried several combinations including the combination below:
Root[1] (Process)
+- ExampleSource[1] (ExampleSource)
+- DataStreamProvider[1] (DataStreamProvider)
+- BayBoostStream[0] (BayBoostStream)
+- NaiveBayes[0] (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.
Thanks!
