Web1.2 Biological Challenges to Backprop There are numerous strong biological arguments suggesting backpropagation is implausible in the brain. The neurobiologists’ concern has been articulated as early as 1989, in a paper published by David Stork (of Stanford) entitled “Is backpropagation biologically plausible?” Stork and others WebMar 2, 2024 · We propose a biologically plausible model for complex cells that learns to pool inputs from simple cells based on the presentation of natural scene stimuli. The model is a three-layer network with rate-based neurons that describes the activities of LGN cells (layer 1), V1 simple cells (layer 2), and V1 complex cells (layer 3). ...
