It got Best Paper at CoRL. In the paper, we decoupled the KL vs state marginal hypothesis explicitly, and empirically shown that matching state marginal mattered more. Link: https://arxiv.org/abs/1911.02256
GKD (2023) paper by @agarwl_ @OlivierBachem is also great!
If you are into OPD, check out our 2019 paper "Divergence Minization Perspective on Imitation Learning". I like to use a single formula/table to explain how methods relate each other, from fundamentals.
Or read DAgger (2010) :)

@shaneguML my favorite paper back in the day 😎

@shaneguML @agarwl_ @OlivierBachem That’s awesome congrats!
