Implementing an operator

lmsasu

Hello all,

How could one implement a custom operator (e.g. a fuzzy ARTMAP classifier) and further add it to the operators group in RapidMiner? I guess that it should be implemented in Java, by deriving some specific classes/implementing RM interfaces. Where could I find such an example or (better) documentation in this subject?

Thanks,
Lucian

Later edit: after digging the web, it seems that for RM 5 the white paper (http://rapid-i.com/component/page,shop.product_details/product_id,52/flypage,flypage.tpl/pop,0/option,com_virtuemart/Itemid,180/vmcchk,1/) is the authoritative resource. The RapidMiner 4.6 document contains a section dedicated to this area. Is this section deprecated/outdated? I intend to ask to my students to implement some ML-based models and integrate them into RM. At first glance, Weka seems to be more easily extended with custom models.

Hello lmsasu

Yes, the doc of 4.6 is outdated. It will be quite hard to create a plugin with only this reference and examples (for rm5.x at least). I have absolute no authority to speak on this subject, but if you contact rapid-i directly (contact@rapid-i.com), state who you are and that you need the document for academic purpose, they may give you a discount or allow the distribution of one bought document among the students for the time of the lecture.

I'd try it, but as I said, I have no authority here (i am just a regular enduser like you).

greetings,

Hi lmsasu,

implementing a RapidMiner operator is rather easy. There is some overhead of creating an extension, but the white paper comes with a template so you basically implement a Java class and run an ant target. Just have a look at the white paper.
