Subject Using .mvc file to train a classifier
Date Tue, 10 May 2011 10:44:55 GMT
Hi,
I am a MAHOUT Beginner.
I used weka to generate a .arff file from the training data.
 ./bin/mahout  arff.vector --input ../X4.classifier.arff --output
raghavan_test_output/ --dictOut label_bindings

I found the label_bindings file to be empty. I could nt understand the
reason for it and also wondering what the content of the label_bindings
files should be..

I had a .mvc file generated in the directory i mentioned. 

Can I use this file to train a classifier using the command shown below ?
./bin/mahout trainclassifier --input
raghavan_test_output/X4.classifier.arff.mvc --output X4model -type cbayes

I am pasting the logs below which i got while executing the command above
