The paper introduces Variational Flow Matching (VFM), a new formulation for flow matching that leverages variational inference. This approach yields a method called CatFlow, which is designed for categorical data and achieves strong results on graph generation tasks. The VFM objective approximates the posterior probability path, allowing it to capture both deterministic and stochastic dynamics. The paper also relates VFM to score-based models and derives a bound on the model likelihood based on a reweighted VFM objective. Experimental evaluation of CatFlow on abstract and molecular graph generation tasks demonstrates its effectiveness, surpassing or matching state-of-the-art performance in all cases.

The paper creates a new way to match flows using something called variational inference. This helps create a method called CatFlow that’s good at working with categorical data and makes nice graphs. The new approach is like a game where you try to find the best path, which is useful for things like generating molecules or drawing diagrams. The paper also shows how this new way relates to other methods and makes predictions about how well it will do. Finally, they tested CatFlow on some problems and found that it works really well!
