Fast covariance-free spatiotemporal modeling via coarse-to-fine learning
Daisuke Murakami
Scalable spatiotemporal modeling remains challenging because conventional methods rely on covariance models that tightly couple spatial representation and temporal inference, often…

Scalable coarse-to-fine spatial downscaling
Daisuke Murakami, Yongwan Chun, Takahiro Yoshida +1
This study proposes coarse-to-fine downscaling (CF-DS), a scalable spatial downscaling method extending coarse-to-fine spatial modeling. Unlike conventional spatial-statistical dow…

Coarse-to-fine spatial GLMM for scalable prediction and multiscale analysis
Daisuke Murakami, Alexis Comber, Takahiro Yoshida +3
We develop a coarse-to-fine generalized linear mixed model (CF-GLMM) for scalable spatial prediction of exponential-family responses. CF-GLMM extends coarse-to-fine spatial modelin…
