Wavelet Flow Matching for Multi-Scale Physics Emulation

In three linesWavelet Flow Matching (WFM) is a generative emulator for multi-scale physical systems governed by PDEs. It performs optimal transport directly in the hierarchical wavelet space of a U-Net, without pre-trained autoencoders. On three chaotic fluid dynamics systems, WFM outperforms SOTA models in long-horizon stability, accuracy, and spectral coherence.
