Abstract
En 中文
• A novel spatio-temporal irradiance imputation based on a diffusion model. • Physics-based prefill provides better initialization for missing data. • Wavelet- and graph-based multimodal features enhance coherence and accuracy. • Demonstrated superior accuracy and robustness on all regions and missing rates.
