Schematic of the GC-UNO architecture and the U-NO model. The U-NO is highlighted by a yellow box, and the loss functions are indicated by red boxes. NLFFF data are visualized using color maps, while the output from the U-NO is displayed in gray scale. The red dashed arrows represent downsampling of the data, the green dashed arrows denote upsampling, and the black dashed arrows indicate data concatenation.
