Source paper for clustering algorithm?

[huynq55-v2]

Could you please let me know the research paper that this repository's clustering algorithm in src/clustering is based on?

i've synthesized results from quite a few papers in the implementation of the clustering algorithm, but the most important are cited in main.rs. the main ideas are:

• every street is kmeans clustered using potential aware imperfect recall using EMD
• for Flop and Preflop, we use optimal transport via sinkhorn regularization to calculate EMD
