ArrayIndexOutOfBoundsException on classifyInstance, please help

[aneuryzma]

hi,

I'm getting a java.lang.ArrayIndexOutOfBoundsException: 3

at this line of my code: classifier.classifyInstance(unlabeled.instance(20) );

I've a training data set train.arff and a dataset to label test.arff

Since I'm quite stuck, and I don't understand where the issue is, I have some questions:

- unlabeled.arff is supposed to have the class attributes ? Or should I remove it from the instances ?

- My test.arff is exactly in the same format of training.arff. Same relation, etc... Should something be different instead ?

- I'm applying to both files the same filter. So I really dunno what's wrong here. Please check the code for more details: #1726522 - Pastie

and these are the files:
train.arff #1726525 - Pastie
test.arff #1726527 - Pastie

thanks

I'm quite stuck.
thanks

Post the relevant code...most people won't click on downlaods.

Then show us which line the error is occurring on.
I have no idea what an arff file is, so a description of what the code you post is supposed to be doing might help.

i've solved, it was because of not correctly assigned filter to the test.arff
