Hi all, I have a quick question. I am trying to build a decision forest using Mahout’s partial implementation and then predict using that.
I run the command like this $HADOOP_HOME/bin/hadoop jar …/mahout-examples-<version>-job.jar org.apache.mahout.classifier.df.mapreduce.TestForest -i <test_data> -ds <descriptor_file> -m ob -a -mr -o predictions It works fine and outputs the confusion matrix in the log and creates a folder called predictions in HDFS with a file called testing.out. Now can someone please tell me what the format of this file is it doesn’t seem to be a text file. It seems to be a binary file, but not sure in what format. How do I read this predictions output file? Thanks Prabhu
