Marty Kube updated MAHOUT-1163:
-------------------------------
Status: Patch Available (was: Open)
The attached patch generates and reads meta-data files in a JSON format.
I've ran through the partial implementation examples and the documentation does
not need changes.
This patch is step towards supporting ARFF in the RF classifier.
> Make random forest classifier meta-data file human readable

> The RF classifier has as a Describe utility which figures out a description
> of a data set (how many attributes, types, and enumerated values, etc...) and
> writes this meta-data to file for later use during training or testing.
> The file format is binary. That means the only way to generate it is with
> the Describe utility and it is hard to modify. If the format was human
> readable it is then possible to modify/generate the meta-data by hand.
> This will also make it easier to support standard formats such as ARFF.
