Is there something like clusterdump for Naïve Bayes?
I'm somewhat new to Mahout and am running through the Mahout 0.7 examples.
So far I've gone through classify-20newsgroups.sh for Naïve Bayes
and cluster-reuters.sh for K-Means Clustering. I really like
the clusterdump function in the K-means example because it helps me
understand what the main drivers behind each cluster are. Is there a
similar function anywhere to see the top drivers behind the Naïve Bayes
classification in the naiveBayesModel.bin file?
I suppose I could write some of my own code to parse out the alphaI,
weightsPerFeature, weightsPerLabel, perLabelThetaNormalizer values from
the naiveBayesModel.bin similar to code in
the org.apache.mahout.classifier.naivebayes.NaiveBayesModel class.
However, I'd much rather reuse someone else's code if it exists already.
Thanks,
Adam
