Implementing Precision & Recall using LIBSVM in Java

Question

I developed a datamining application using libsvm.jar (independently from weka). But I can't find how to implement Precision/Recall (in java) to validate my model performance.

Are there any API's to include or methods to use in Libsvm Classes ?

Knowing that such capability is included in C and Python versions of LIBSVM (but not in java).

Answer 1

for this we require weka.

Weka and libsvm are available in one package

follow this link for combining Weka and libsvm http://www.cs.iastate.edu/~yasser/wlsvm/

weka is good calculating ROC,recall,etc.... and libsvm is good for classification, regression,etc...
