Misalignment Between Backpropagation and the Hierarchy of Brain Responses to Images
Researchers using fMRI and MEG data found that while backpropagated gradients in deep neural networks can predict brain activity in higher visual cortex, their spatial and temporal organization fundamentally diverges from how the human brain processes visual information. This suggests that although artificial and biological neural networks may learn similar representations, they employ distinctly different learning mechanisms.
