Moving Beyond Diffusion: Hierarchy-to-Hierarchy Autoregression for fMRI-to-Image Reconstruction
Researchers introduce MindHier, a new framework for reconstructing visual images from brain fMRI signals using hierarchical autoregressive modeling instead of diffusion methods. The approach achieves 4.67x faster inference while improving semantic accuracy by aligning neural hierarchies with image generation stages, mimicking human visual perception.
