MIN-FU YANG commented on SPARK-16280:
-------------------------------------
I implemented histogram_numeric according to the Algorithm I & II in the paper:
Yael Ben-Haim and Elad Tom-Tov, "A streaming parallel decision tree algorithm",
J. Machine Learning Research 11 (2010), pp. 849--872.
After doing some benchmarking, I come out an optimal solution and ready for
review: https://github.com/apache/spark/pull/14129
