Decision trees and diffusion models are unified via a shared Global Trajectory Score Matching principle, yielding TreeFlow for tabular generation and DSMTree for distilling tree logic into networks.
A TreePathEncoder class converts the decision path of any sample into a sparse vector encoding, where the value at an index is the inverse of the node’s depth
