Preconditioned Flow Matching improves generative model training

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new technique called Preconditioned Flow Matching (PFM) to improve the training of generative models. PFM addresses an optimization bottleneck where ill-conditioned covariance matrices in intermediate distributions lead to slow convergence. By transforming the target distribution into a more isotropic representation before training, PFM reshapes the flow matching path and enhances its conditioning. Experiments on various image datasets, including MNIST and higher resolution images up to 512x512, demonstrate that PFM improves diagnostic metrics, sample quality (FID, MMD), and precision/recall compared to standard flow matching.

    Preconditioned Flow Matching

    arXiv:2603.02337v3 Announce Type: replace-cross Abstract: Flow matching (FM) learns vector fields by regressing stochastic velocity targets along intermediate distributions $p_t$. We identify a geometric optimization bottleneck in this regression problem: when the covariance $\Si…
