Sean Owen updated MAHOUT-997:
-----------------------------
Fix Version/s: (was: 0.6)
> Make splitData smart enough to not consider a CSV header to be part of the
> data
> -------------------------------------------------------------------------------
>
> Key: MAHOUT-997
> URL: https://issues.apache.org/jira/browse/MAHOUT-997
> Project: Mahout
> Issue Type: Improvement
> Components: Integration
> Affects Versions: 0.6
> Environment: OS X
> Reporter: Andrew Harbick
> Priority: Minor
>
> If you do something like:
> MAHOUT_LOCAL=1 $MAHOUT_HOME/bin/mahout splitDataset --input all.csv --output
> split --trainingPercentage 0.9 --probePercentage 0.1
> The header row from your CSV will end up with 90% chance in your training
> data and 10% chance in your evaluation data. To use a tool like
> trainlogistic or runlogistic the header file is needed in both.
> Perhaps add an argument to splitData to duplicate the header line?
