Data-Stream-Plugin (formerly Concept-Drift-Plugin)

Hi there,

Have you seen the series plugin for Rapidminer 5? Rapidminer 4.0 is only dimly remembered, and even less supported!

Thank you for your reply. I have installed the Series Plugin but could not find anything for drift detection. Is there any chance to use adaptive window-sizes in RM?
Best Regards

PS: What I have found - and what is pretty cool - are operators for Bagging!! I really start to like that tool.

Hi there,

I seem to remember a sliding window XValidation operator in the Series plugin, that might help...

Hope so!

Hi haddock

Thanks for your help. I have already discovered that one. But this operator uses a fixed window, which makes no sense in presence of a stable concepts. Therefore it would be better to have an adaptive window. I just read about a method which is called drift detection method and is used to determine the point in a time-series at which a concept drift has occurred. Basically it monitors the classification error which will decrease over time in the absence of concept drift. The detection has two steps. First a warning(1) and then a point where it is almost certain(2) that a concept drift has occurred. If this happens the data instances between (1) and (2) are used for building a new prediction model. Sounds pretty easy, that is why I thought there might be an implementation for RapidMiner?

Hi all,

I have one question. Can you use Rapid Miner for data steam minig (Algorithms such as VFDT Very Fast Decision Tree)? Is there a tutorial available, anywhere?
