[Mulan-list] Problem with float target

[Enrique M. A. <ema...@si...>]

Hi!
I am trying to run the "MulanExp2.java" example using the andro.arff.
I have created the corresponding xml file.

When I try, there is a problem because the targets (6 classes) are float.

How can I run this example using these data (real data target)?

Thank you
Marcelo.-


This is the error:
