Hi filipags,
welcome to the Rapidminer community! A good start to get familiar with Rapidminer is to watch the introduction videos on the rapid-i website:
http://rapid-i.com/content/view/189/198/lang,en/.
Then you can also take a look at the RM Tutorial that you can find in the Help menu of RM (search in the forum for post regarding the tutorial too).
Finally you'll find a lot of example an demonstration processes regarding different data mining task and features of RM through the Community Extension. In order to get access to them, install the
RM Community plugin via the RM updater and follow the simple HowTo on
www.e-lico.eu. You do not need a MyExperiment account to get access to RM workflow, though.
However, we encourage everyone to share
RM workflows on the
MyExperiment.org portal, which needs an account.
I wish you a good start!
Ciao Sebastian
