[kepler-users] How to integrate Weka into Kepler?

[Ilkay Altintas]

Hi Josep,

Thanks for your proposal to integrate Weka into Kepler. We've been  
considering this as it is needed in Kepler for many projects.

An alternative approach might be integrating Weka Web Services using  
Kepler's WebService actors. Have you looked into Weka4WS at http://grid.deis.unical.it/weka4ws/? 
  I meant to do it a while back, but didn't get the chance.

I would be interested in collaborating with you on this as I need it  
for a research project.

Thank you!
