Misalignment Between Backpropagation and the Hierarchy of Brain Responses to Images 事件

Misalignment Between Backpropagation and the Hierarchy of Brain Responses to Images arXiv:2605.28693v1 Announce Type: cross Abstract: Backpropagation is the core learning mechanism underlying deep learning. However, whether and how this algorithm is implemented in the brain remains highly debated. In particular, while forward activations of pretrained models reliably map onto the cortical hierarchy of visual processing, it is unknown whether backpropagated gradients exhibit a similar correspond
