reflection - LIbSVM of Weka in C# with IKVM -

-

i using weka machine learning library in c# ikvm. far worked well, however, having problem using libsvm package.

the problem appears when want instantiate libsvm classifier in c# (the class not found), advised:

abstractclassifier classifier = (abstractclassifier)java.lang.class.forname("weka.classifiers.functions.libsvm").newinstance();

what tried:

  • add the libsvm.dll , weka.dll project (converted libsvm.jar , weka.jar)
  • merge libsvm.jar , weka.jar 1 dll , add project (using ikvm or ilmerge)

note package installed since appears in result of 

wekapackagemanager.getinstalledpackages();

has every succeeded using weka libsvm in c# using ikvm?

thanks, botond

i hava same problem ,but found solution website:here.

i use weka.jar(version 3.6) , libsvm package weka 3.8 {home}/wekafiles/packages/libsvm

step 1. need: weka.jar, libsvm.jar(libsvm/libsvm.jar), libsvm.jar (libsvm/lib/libsvm.jar).

step 2. rename libsvm.jar libsvm1.jar.

step 3. run in ikvm: open command line , go ikvm's bin folder

    ikvmc.exe -sharedclassloader -target:library weka.jar libsvm.jar libsvm1.jar

step 4. reference generated weka.dll in c# project.

step 5.sample code in c#

libsvm svm = new libsvm(); svm.setoptions(weka.core.utils.splitoptions("-s 3 -k 2 -d 3 -g 0.0 -r 0.0 -n 0.5 -m 40.0 -c 1.0 -e 0.001 -p 0.1 -seed 1")); svm.buildclassifier(dataset);
