convert mahout random forest classification output to readable

Question

I am learning the mahout random forest with tutorial in mahout site: http://mahout.apache.org/users/classification/partial-implementation.html

but when all jobs finishes successfully my output file is like this:

@1@.@0@

@1@.@0@

@0@.@0@

@1@.@0@

@1@.@0@

@0@.@0@

@0@.@0@

@0@.@0@

how can I convert it to human readable output?

Answer 1

finally i found that this numbers are the code of labels.

we can change them to labels.

after this code in TestForest.java example:

classifier.run();

get the results:

double[][] results = classifier.getResults();

the second column is the prediction. change it to label with this code:

Dataset dataset = Dataset.load(getConf(), datasetPath);
for (double[] res : results) {
    dataset.getLabelString(res[1]);
}
