(New here, nice to meet you.)
I am trying to set the number of bins in XGBClassifier by using max_bin, but something looks completely off…
My tree_method is set to hist. I try changing max_bin to various values, including extremely small and large ones, but the results are always almost unchanged (they seem to change to a tiny degree).
I have three questions on this:
Am I missing something?
Is the “max” in max_bin just a suggestion, and if yes then how do we set the exact number of bins?
How can I find out the number of bins actually used by the model?
