A new supervised learning method, termed counterstream learning, has been proposed for deep associative networks. This approach aims to be more biologically realistic than traditional backpropagation by utilizing the same neural pathways for both forward and error signal propagation. The method involves initiating activity waves from input and output layers that meet in a hidden layer, using local Hebbian-type learning rules to link activity patterns and reduce errors. Preliminary results on the binarized MNIST dataset show competitive test accuracy compared to more complex architectures, despite incomplete hyperparameter optimization. AI
