Increment new data in decision tree

I have three csv files with different years (2001, 2005, 2009), in relation to the consumption of electric energy in the USA.

I've managed to create the ranking model of the year in 2001, but now wished to update the model incrementing data from 2005. I would like to update the model with incremental data.

someone knows how to do this?

Help me please....

Hi,

the decision tree is not an updatable model. You will have to relearn a new one on the updated training data. The only updatable models in the core of Studio currently are k-NN and Naive Bayes.

Thank you for the reply...

And can you tell me how this is possible in K-NN and Naive Bayes? with the update model?

I tried and couldn't ...

Hi,

see the following example process which you just need to save in your repository:

Hi,

I'm very grateful Marco Boeck for help me.

To add a third dataset this process, my code xml is the more correct?
After running the first process adds the saved dataset (retrieve new) and add a new dataset (generate nominal data).

Rapidminer supports incremental clustering and incremental association rules? For incremental Clustering, I use the cobWeb algorithm with an extension to Weka?

Could provide a simple example for both?
