Researchers have developed a new Vision Transformer architecture called Non-Uniform ViT (NUViT) specifically designed to handle Fourier-space data. Unlike standard ViTs that use Cartesian grids, NUViT employs a redesigned tokenization, data representation, and positional encoding method to better capture the structure of Fourier-domain information. Experiments across various tasks, including image classification, crystal lattice identification, MRI annotation, and cryo-EM analysis, demonstrate NUViT's superior performance in understanding this type of data compared to conventional architectures.
