My current understanding is that Modicum used these sources for to make its buckets

paper 3: evaluating state space abstraction
cluster turn(earth movers distance over equity distribution on all rivers) and river (clustering histograms of equity vs 8 ranges on the river by using k means and euclidean distance)
paper 2: earth movers distance
bucket flops by clustering histograms of how likely they are to transition into bucket n on the turn (keeping same turn/river buckets as paper 3)
paper 1: hierarchical abstraction
cluster public flop boards (not including our hole cards) by clustering histograms of how likely flop board plus holecard transitions into bucket n on the flop(using the previously computed abstraction from paper 2)
I haven't gotten through how they then cluster public+holecards on the flop/turn/river and I may not be entirely correct on this part
I was under the impression that pluribus used the same buckets as modicum, but I could look into it
