Beyond Straightness: Non-Crossing Flow Matching via Quantile AlignTree Coupling

Quantile AlignTree Flow Matching (QAT-FM), an efficient structured coupling strategy that constructs a hierarchical coupling between a Gaussian prior and the target data distribution via a quantile-aligned tree structure, is proposed, enabling scalable training for large-scale high-dimensional generative tasks.
