[jira] [Updated] (MAHOUT-785) Universal input file format for
classifier algorithms in Mahout
[ https://issues.apache.org/jira/browse/MAHOUT-785?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen updated MAHOUT-785:
-----------------------------
Affects Version/s: (was: 0.6)
I think this is a fairly open-ended item. It's not clear to me that these different algorithms operate on logically the same input, though I imagine the command line options and such could be more standardized. Do you have particular views on concrete changes to this end?

> I think a universal input file format is much more convinient for users, especially command line users, and we should even consider use some universal command line options for the classification algorithms, such as options for target/predictor variables and their types. Then users can prepare their data once, and build different models to get the best one. Currentlly we should consider the following:
> 1. SGD LogisticRegression
> 2. NaiveBayes
> 3. Bayes
> 4. Random Forest
