SVM light

Hello all,

Am just learning Rapidminer for text classification.

I am glad to see several SVM possibilities in rapidminer but miss SVM light in there. Is it available or does someone have a workaround?

Thanks!

    I am not aware of an implementation like this in RapidMiner.

    Why can't you use the standard RapidMiner SVMs?

    I have seen that SVM light is really fast on the same data set (in another proprietary software) as compared to the SVM possibilities in rapidminer. Hence my interest in getting SVM light in rapidminer

    I only saw a C implementation of it. Is there a Java implementation?

    If so you might be able to add it to rapidminer. If you are familiar with java Rapidminer is easy to extend.

    You can find a guide here: http://rapidminer.com/wp-content/uploads/2013/10/How-to-Extend-RapidMiner-5.pdf

    Of course feel free to ask questions

    Thanks!

    There is a Java wrapper for SVM light in C (example: http://nlp.stanford.edu/nlp/javadoc/jsvm/jsvm.Svm.html)

    Would this make it easier?

    Small update here:

    actually the standard SVM of rapidminer seems to use SVM-Light. The SVM is calling mySVM by Stefan Rüping. This is using the SVM light implimentation. See: http://www-ai.cs.uni-dortmund.de/SOFTWARE/MYSVM/index.html
