    Abstract: A distributed processing system includes a plurality of lower-order aggregation networks and a higher-order aggregation network. The lower-order aggregation networks include a plurality of distributed processing nodes disposed in a ring form. The distributed processing nodes generate distributed data for each weight of a neural network of an own node. The lower-order aggregation networks aggregate, for each lower-order aggregation network, the distributed data generated by the distributed processing nodes. The higher-order aggregation network generates aggregated data where the aggregation results of the lower-order aggregation networks are further aggregated, and distributes to the lower-order aggregation networks. The lower-order aggregation networks distribute the aggregated data distributed thereto to the distributed processing nodes belonging to the same lower-order aggregation network. The distributed processing nodes update weights of the neural network based on the distributed aggregated data.
