Neuroscience-inspired diffusion model explains visual cortex inference

Researchers have developed a novel model that bridges neuroscience and machine learning by explaining perceptual inference in the primary visual cortex (V1) through the lens of diffusion models. This model, based on sparse coding with a specific prior over latent variables, effectively mimics the structure of horizontal connections in V1. When trained on natural images, it demonstrates strong denoising capabilities, comparable to standard diffusion architectures, and offers mechanistic insights into how recurrent neural circuits generate realistic image features.
