Subject [jira] [Updated] (HAMA-612) BSP-based online collaborative filtering algorithm
Date Sun, 14 Jul 2013 11:26:48 GMT

     [ https://issues.apache.org/jira/browse/HAMA-612?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ikhtiyor Ahmedov updated HAMA-612:

    Attachment: data_gen.py

Attached very first version of online cf without considering features and also attached small
data set from movie lens converted to accessible form(ratings5K.dat). Would like to ask for
your help, since when I am testing with 10M dataset converted with data_gen.py script online
cf takes very long time in local mode (sorry, :( I don't have access to cluster). I will add
features and other versions. Thanks in advance
