---------------------------------------
Summary: Refine incomplete AUC (classification) implementation
Key: HIVEMALL-90
URL: https://issues.apache.org/jira/browse/HIVEMALL-90
Project: Hivemall
Issue Type: Improvement
Reporter: Takuya Kitazawa
Assignee: Takuya Kitazawa
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 compute and merge partial results
in an arbitrary order.
