Dear all,
I tried to learn a Decision Tree but after it starts the learning process and after I receive the error: “ArrayIndexOutofBoundsException” and the process stops.
Can anyone tell me what it means?
Thanks

Dear Misha,
thanks for your help. I’ve about 1.000 unique values so I think to use other tecniques like neural networks.
