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 Fix For: 0.6 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? -- This message is automatically generated by JIRA.
