hi,
i am a newbie to mahout(0.7).i am able to successfully create a model by the command below:-
bin/mahout trainnb -i /user/cloudera/MahoutWeighted/1_FactWt-train-vectors -el -o /user/cloudera/MahoutWeighted/model -li /user/cloudera/MahoutWeighted/labelindex -ow
....
but i am unable to use that model...when i am feeding the model with test data in the same way,i trained it..i am not able to get the correct confusin matrix..can anyone please tell me how to use the model created..it would be a great help to me
