Researchers have developed CAESAR-LDAR, a novel error-controlled multivariate learned compressor designed for scientific simulations. This system enhances existing compressors by incorporating a trainable orthogonal transform to reorganize latent channel dependencies and a causal autoregressive prior to model remaining spatial structure. Experiments on combustion, climate, and turbulence data demonstrate that latent decorrelation is most effective for linear cross-channel dependencies, while autoregressive modeling excels with local spatial structures, with their combination yielding strong rate-distortion performance.
