    Default out of memory error in weka

    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.
