Question about position_bins

[robhowley]

Hi,

I'm trying to understand the implementation differences between this repo and lightgbm. Does

position_bins = 12       : this denotes the maximum positions taken into account.

effectively serve the same as lambdarank_truncation_level in the newer releases of lightgbm? Looks like they each cap the number of results from a given query we look at. Wanted to confirm.
