Researchers have developed a novel method called modulo error routing to extend Error Diffusion (ED) for use in biologically plausible dual-stream neural networks that adhere to Dale's principle. This approach allows for effective credit assignment in both supervised classification and reinforcement learning tasks. The method achieved a 96.7% accuracy on the MNIST dataset and a 61.7% baseline on CIFAR-10 for classification, while also demonstrating competitive performance in reinforcement learning tasks when integrated with Proximal Policy Optimization (PPO). The study highlights task-dependent bottlenecks in credit assignment, which were revealed through ablation analysis on different datasets. AI
