This PR marks
quantile-per-tree
parameter of Random Forest for deprecation. Enabling quantile computation per tree has significant performance impact without much accuracy gain. Similar levels of accuracy can be achieved with higher number of bins for global quantiles. Therefore this feature would be removed from subsequent release.This PR also removes three previously deprecated RF parameters:
seed
was deprecated in 0.16 and was planed to be removed in 0.17min_rows_per_node
was deprecated in 0.17 and was planed to be removed in 0.18rows_sample
was deprecated in 0.17 and was planed to be removed 0.18Also minor correction in documentation.
