The approach scales to reinforcement learning and reveals task-dependent ablation effects, offering a biologically plausible alternative for neural network training.", "body_md": "Backpropagation relies on weight transport, which biological circuits likely cannot implement. Sakana AI's Error Diffusion sidesteps that constraint, training dual-stream excitatory/inhibitory networks that obey Dale's principle. This piece breaks down how modulo error routing scales the rule from MNIST to CIFAR-10 and reinforcement learning, and what its task-dependent ablations reveal.\n\nThe post [Sakana AI’s Error Diffusion Trains Dale-Compliant Dual-Stream Networks, Reaching 96.7% MNIST and 61.7% CIFAR-10 Without Backpropagation](https://www.marktechpost.com/2026/07/17/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-96-7-mnist-and-61-7-cifar-10-without-backpropagation/) appeared first on [MarkTechPost](https://www.marktechpost.com).", "url": "https://wpnews.pro/news/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-7", "canonical_source": "https://www.marktechpost.com/2026/07/17/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-96-7-mnist-and-61-7-cifar-10-without-backpropagation/", "published_at": "2026-07-18 06:32:43+00:00", "updated_at": "2026-07-18 06:33:49.320957+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "neural-networks", "ai-research"], "entities": ["Sakana AI", "MarkTechPost"], "alternates": {"html": "https://wpnews.pro/news/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-7", "markdown": "https://wpnews.pro/news/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-7.md", "text": "https://wpnews.pro/news/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-7.txt", "jsonld": "https://wpnews.pro/news/sakana-ais-error-diffusion-trains-dale-compliant-dual-stream-networks-reaching-7.jsonld"}}
