使用扩散桥对流体流动进行非配对下采样（英文版）

英文标题：Unpaired Downscaling of Fluid Flows with Diffusion Bridges中文摘要：本文提出了使用基于扩散映射的生成模型来降低理想地球物理流体模拟的方法，生成高分辨率图像，避免额外的校准或培训，并适用于多个源和目标域的组合，而不需要训练新模型。英文摘要：We present a method to downscale idealized geophysical fluid simulationsusing generative models based on diffusion maps. By analyzing the Fourierspectra of images drawn from different data distributions, we show how one canchain together two independent conditional diffusion models for use in domaintranslation. The resulting transformation is a
