CD-TVD: Contrastive Diffusion for 3D Super-Resolution with Scarce High-Resolution Time-Varying Data
CD-TVD pretrains a contrastive encoder and diffusion super-resolution network on historical simulation data, then fine-tunes with a single high-resolution timestep to reconstruct all low-resolution timesteps in a new scenario.
