  • Publication number: 20220261620
    Abstract: A distributed processing node transmits distributed data for M groups as intermediate consolidated data from M communication units to a distributed processing node. A distributed processing node generates, for each group, updated intermediate consolidated data from the received intermediate consolidated data and distributed data, and transmits the updated intermediate consolidated data from the M communication units to a distributed processing node. The distributed processing node transmits the received intermediate consolidated data to a distributed processing node as consolidated data. The distributed processing node transmits the received consolidated data to a distributed processing node. Each of the distributed processing nodes updates weights of a neural network, based on the consolidated data.
