Wavelet Flows Speed Universe Reconstruction

Wavelet Flows Speed Universe Reconstruction

Cosmo3DFlow uses 3D wavelet transform and flow matching for efficient cosmological inference from N-body simulations. Addresses sparsity via spectral compression, enabling 50x faster sampling than diffusion models. Samples initial conditions in seconds at 128^3 resolution.
