Class CBayesThetaNormalizerReducer
java.lang.Object
org.apache.hadoop.mapred.MapReduceBase
org.apache.mahout.classifier.bayes.mapreduce.cbayes.CBayesThetaNormalizerReducer
- All Implemented Interfaces:
- java.io.Closeable, org.apache.hadoop.mapred.JobConfigurable, org.apache.hadoop.mapred.Reducer<StringTuple,org.apache.hadoop.io.DoubleWritable,StringTuple,org.apache.hadoop.io.DoubleWritable>
public class CBayesThetaNormalizerReducer
- extends org.apache.hadoop.mapred.MapReduceBase
- implements org.apache.hadoop.mapred.Reducer<StringTuple,org.apache.hadoop.io.DoubleWritable,StringTuple,org.apache.hadoop.io.DoubleWritable>
Can also be used as a local Combiner beacuse only two values should be there inside the values
