Change and Deviation detection

ruser

I understand that 'Change and Deviation detection' is one of the main possibilities with the Data mining.
Does Rapidminer support it? If yes, please provide details about it.

Hi,

RapidMiner supports 'Change and Deviation detection'. What details are you interested in? RapidMiner does not have a monolothic ChangeAndDeviationDetectionOperator. Every RapidMiner process is made up of several Operators that you combine to suit your needs. Also, you are asking a very broad question here. Where should I start?

If you have specific questions, I will be happy to answer them.

Best,
Simon

Good! The problem is that I do not find any detailed examples in the literature on using the 'Change and Deviation detection', compared to the broad coverage on other main 'Data mining' aspects.
I just want to try some examples to get familiar with it. Could you probably tell me some examples on how I can detect deviations compared to the previosly measured or normative values?

A good starting point to learn more about change detection and the related topic of concept drift are the following Wikipedia entries:

  http://en.wikipedia.org/wiki/Change_detection
  http://en.wikipedia.org/wiki/Concept_drift

Im my publications on concept, you will also find further explanations and references:

Thanks for the references. But my requirement is to play with some examples using the Rapidminer. Can you quote some operators (or even a sample process definition) in Rapidminer which can be used for 'Change and Deviation detection?

Hi,
unfortunately we don't have such an example right now. But if you find some data, for example in the UCI repository, and build a usefull process around it, feel free to contribute it. We will then add it for other users having the same questions.

Greetings,

In other words, can I assume that 'Change and Deviation' is an area which has to be newly exploted by the Rapidminer community, and there are no operators in the Rapidminer that are related to the 'Change and Deviation'?
If my conclusion is wrong, please give me the list of some important operators which can be used for it.
