Researchers have introduced Manifold-Aligned Generative Transport (MAGT), a novel method for generating high-dimensional data that concentrates near a low-dimensional structure. Unlike diffusion models that require iterative denoising or standard normalizing flows needing invertible maps, MAGT directly transports data from a low-dimensional base distribution. The approach compares data and generator-induced scores at a selected Gaussian smoothing level, approximating the score through importance sampling. Experiments on synthetic, image, and tabular data demonstrate MAGT's effectiveness in terms of fidelity, support alignment, and sampling cost when compared to diffusion models, flow-matching, and adversarial baselines.
