H-GLow: Accelerating Graph Generation via Hazard-Guided Discrete Flow Matching
Read the original on arXiv Machine Learning →H-Glow is a hazard‑guided framework that accelerates graph generation by decomposing Continuous‑Time Markov chain generators into hazards and conditional jump distributions. It plans graph edits and dynamically adjusts sampling time based on graph activity, allowing pretrained graph DFM models to produce higher‑quality graphs with fewer steps. The authors also propose a new graph DFM model that directly predicts hazards and conditional jumps, whose training objective cleanly splits into hazard matching and weighted jump prediction, and demonstrate its effectiveness on molecular and synthetic graph benchmarks.
