Matthias Boehm commented on SYSTEMML-700: ----------------------------------------- thanks for the clarification - this requires probably a larger discussion but I would like to generalize this to all our classification algorithms, especially decision tree/random forest which require heavy input preparation. > Inflexible category labels for Multinomial Logistic Regression > -------------------------------------------------------------- > > Key: SYSTEMML-700 > URL: https://issues.apache.org/jira/browse/SYSTEMML-700 > Project: SystemML > Issue Type: Bug > Components: Algorithms > Reporter: Jeremy > Priority: Minor > Original Estimate: 4h > Remaining Estimate: 4h > > The Logistic Regression algorithm requires that category labels be labeled as > 0 up to the number of classes-1. It should be able to handle any set of > category labels provided by the user. B_out should have the appropriate size > regardless of the values of the labels given, and the algorithm should also > preserve the original labeling for the user. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
