Researchers Use AI to Generate Images Based on People's Brain Activity

This study was a peek into the internal processes of diffusion models, the researchers concluded, saying that the study was the first to provide a quantitative interpretation of the model from a biological perspective. For example, there is a diagram that the researchers created showing the correlation between stimuli and noise levels in the brain. The higher-level the stimuli, the higher-level the noise level would be, and the higher resolution the image would be. In another diagram, the researchers show the engagement of different neural networks in the brain and how it would de-noise an image to reconstruct it.
