    Riemannian MeanFlow for One-Step Generation on Manifolds

    Researchers have introduced Riemannian MeanFlow (RMF), a novel method for generative models operating on Riemannian manifolds. Unlike previous approaches that require extensive simulation for sampling, RMF enables one-step generation by defining an average-velocity field through parallel transport. This method is practical in a log-map tangent representation, reducing computational costs and avoiding trajectory simulation. Experiments on various manifolds, including spheres, tori, SO(3), and SE(3), show that RMF achieves competitive sampling quality with improved efficiency and lower costs, and also supports conditional generation.

    Riemannian MeanFlow

    Researchers have developed Riemannian MeanFlow (RMF), a new framework for generative modeling on Riemannian manifolds. This method significantly reduces the computational cost of generating samples, requiring only one forward pass compared to the dozens or hundreds needed by existing diffusion and flow models. RMF achieves comparable sample quality in applications like DNA sequence design and protein backbone generation while enabling more efficient reward-guided design processes. AI
