Robin Anil updated MAHOUT-60:
-----------------------------
Attachment: MAHOUT-60.patch
This is the latest diff against the trunk
Changes:
*Added a Result Analyzer Class to generate Classification Statistics. Currently
generates Confusion *Matrix and Percentage accuracy. It will be extended to
include (Precison, Recall, RMSE , Relative Absolute Error, Kappa Statistic)
*All such instances extends a Summarizable Interface
Before using this patch please use MAHOUT-9 (Implement MapReduce
BayesianClassifier) patch and the instructions given above.
The number of reducers are limited to 1 at the moment. Will need to figure out
a way to read intermediate result
You can directly run the TestTwentyNewsgroups from the dfs as follows

$bin/hadoop jar <MAHOUT_HOME>/build/apache-mahout-0.1-dev-ex.jar
org.apache.mahout.examples.classifiers.cbayes.TestTwentyNewsgroups -p
