Cosmo3DFlow: Wavelet Flow Matching for Spatial-to-Spectral Compression in Reconstructing the Early Universe
Researchers introduced Cosmo3DFlow, a generative AI framework that combines 3D wavelet transforms with flow matching to reconstruct the early universe from present-day observations. The method achieves 46x faster sampling than diffusion models, reducing computational time from minutes to seconds for cosmological simulations at 128³ resolution.
