An electronic device includes: at least one memory configured to store at least one instruction and a first neural network model; a communicator including communication circuitry; and at least one processor configured to execute the at least one instruction to: receive, by the communicator, information about a second neural network model stored in the external electronic device from the external electronic device; comparing the first neural network model with the second neural network model based on information about the second neural network model; and controlling the communicator to transmit information on a weight between nodes of the first neural network model to the external electronic device based on a comparison between the second neural network model and the first neural network model.
