Zilei Shao, Ian Li, Heng Zhao, Kewei Lian, Guy Van den Broeck, Zhe Zeng, Anji Liu

Combines a diffusion language model with a probabilistic circuit that models dependencies among tokens proposed together. Learns context-dependent token coupling and uses it to decide which discrete tokens to commit in parallel on math and code tasks.
