[jira] [Updated] (HIVEMALL-90) Refine incomplete AUC (classification) implementation

     [ https://issues.apache.org/jira/browse/HIVEMALL-90?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Takuya Kitazawa updated HIVEMALL-90:
------------------------------------
    Description: 
Current implementation cannot handle some merge orders e.g., {0, 2, 1} in case of a test case https://github.com/apache/incubator-hivemall/blob/97bc91247f1a453b6ffb49212800fa601d25c297/core/src/test/java/hivemall/evaluation/AUCUDAFTest.java#L207

This should be refined, and AUC UDAF has to be able to compute and merge partial results in an arbitrary order.
