ABSTRACT: This
paper aims to reduce the communication cost of the distributed learning
algorithm for stochastic configuration networks (SCNs), in which information
exchange between the learning agents is conducted only at a trigger time. For this purpose, we propose the
communication-censored distributed learning algorithm for SCN, namely
ADMMM-SCN-ET, by introducing the event-triggered communication mechanism to the
alternating direction method of multipliers (ADMM). To avoid
unnecessary information transmissions, each learning agent is equipped with a
trigger function. Only if the event-trigger error exceeds a specified threshold
and meets the trigger condition, the agent will transmit the variable
information to its neighbors and update its state in time. The simulation
results show that the proposed algorithm can effectively reduce the
communication cost for training decentralized SCNs and save communication
resources.
