Sakana AI bypasses backpropagation with novel Error Diffusion training

Researchers at Sakana AI have developed a new deep learning training method called Error Diffusion (ED) that bypasses the need for backpropagation. This novel approach adheres to Dale's principle, a biological constraint on neural activity, by using local learning rules and a dual-stream network architecture. The team introduced three key innovations—layer-specific sigmoid widths, batch-centered class error, and asymmetric initialization—which enabled ED to achieve 96.7% accuracy on MNIST and 61.7% on CIFAR-10, marking the first time ED has been successfully applied to convolutional networks.
