out of memory error in weka

[monika]

Hi ,

I am using weka which is a open source data mining software.When I am using large dataset,it gives me out of memory error.



When I am trying to run a J48 algorithm,it gives an out of memory error and it suggesting me to increase Java virtual machine heap size


In the comment promt-(C:\user\xyz> )

I have typed the command



java -Xmx1g -C:\Program Files\Weka-3-6\weka.jar

where
"C:\Program Files\Weka-3-6\weka.jar"-the location of the jar file of weka
But this did not work.

Somewhere I have found the solution as
java -Xmx1g -classpath /some/where/weka.jar


Do I have to edit my class path


I have also tried with editing my class path

My previous class path
.;C:\Program Files (x86)\Java\jre6\lib\ext\QTJava.zip

New one--
.;C:\Program Files (x86)\Java\jre6\lib\ext\QTJava.zip;C:\Program Files\Weka-3-6\Weka.jar

But it also didnt work.

Please let me know how to increase the heap size.

Thank You
Monika

Don't cross-post. It is extremely rude, and your other thread has answers, already.
