WEKA
GUI
To run the WEKA GUI from Hoffman2
- Make sure that you enabled X11 forwarding by including the -Y flag in your SSH command:
$ ssh -Y joebruin@hoffman2.idre.ucla.edu
- Request an interactive node to run on with the following command:
$ qrsh -l i
- Wait for the new node to appear. Your prompt will change from:
[joebruin@login4 ~] $
to something like
[joebruin@n1234 ~] $
- Run the command:
$ java -jar /u/home/FMRI/apps/weka/current/weka.jar
And the current version of WEKA should start up and the GUI will appear.
Command Line
Calling any of the usual WEKA command line tools will work in submitted jobs so long as you properly reference the WEKA jar file at:
/u/home/FMRI/apps/weka/current/weka.jar
A sample command would be
$ java -Xmx2g -cp /u/home/FMRI/apps/weka/current/weka.jar weka.classifiers.functions.SMO -o -T awesome_train_file.arff -t awesome_test_file.arff
where
- -Xmx2g
- calls for 2GB of memory
- -Xmx256m calls for 256MB of memory
- -o
- suppresses the model output
- -T awesome_train_file.arff
- specifies the training file
- -t awesome_test_file.arff
- is an optional testing file for the model
- if this option is not provided, 10 fold cross validation will be done
