[Topic-models] [Mallet][hPAM]To calculate the empirical loglikelihood for held-out data in hPAM model

Hi,

I am now using the Mallet Java api to build hierarchical PAM model. There
is a function
*public void estimate (InstanceList documents, InstanceList testing,int
numIterations, int showTopicsInterval,int outputModelInterval, int
optimizeInterval, String outputModelFilename,Randoms r),*

which seems to build the model and to estimate the test data also. However,
the "testing" part is not really used. Would anybody please kindly inform
me of the way to calculate Empirical Loglikelihood for held-out data using
the hPAM model? Thanks a lot.


Best Regards,
Claire
