Verifying the Model generated by the classifier

Vote count:

0

I am using Mahout Naive bayes classification algorithm to classify the input documents to known categories.

I am able to build the model using mahout commands.

• mahout seq2sparse


• mahout split


• mahout trainnb


• mahout testnb

Test results looks good.

Now, I would like to verify my model with real data.

I am trying below command to verify the ouptut:

 mahout org.apache.mahout.classifier.Classify \
  -m /data/model/ \
  --classify  /data/input.txt \
  --encoding UTF-8 \
  --analyzer org.apache.mahout.vectorizer.DefaultAnalyzer \
  --defaultCat unknown \
  -ng 1 \
  -type bayes \
  -source hdfs

This command is failing with "java.lang.ClassNotFoundException: org.apache.mahout.classifier.Classify".

I have set the mahout core jar and other mahout jars in the classpath. I am using Mahout 0.9.

How to run the classifier in Mahout 0.9 ?
