Better Source, Better Flow: Learning Condition-Dependent Source Distribution for Flow Matching
arXiv:2602.05951v2 Announce Type: replace-cross Abstract: Flow matching has recently emerged as a promising alternative to diffusion-based generative models, particularly for text-to-image generation. Despite its flexibility in allowing arbitrary source distributions, most existing approaches rely on a standard Gaussian distribution, a choice inherited from diffusion models, and rarely consider the source distribution itself as an optimization target in such settings. In this work, we show that principled design of the source distribution is not only feasible but also beneficial at the scale o
This research is emerging now as generative AI models, particularly for text-to-image, mature and researchers focus on refining underlying principles for improved efficiency and quality.
Improving the efficiency and theoretical underpinnings of generative models through optimized source distributions could significantly enhance AI capabilities, reduce computational overhead, and expand application domains.
The shift from default Gaussian source distributions to learned, condition-dependent ones introduces a new optimization vector for flow matching models, potentially leading to more robust and higher-fidelity generation.
