Kind Code:
B2
Abstract:
PURPOSE:To reduce the number of times of repetitive learning and to reduce the number of neuron components by providing a subtractor obtaining an error between study data and an output color signal to the device so as to revise the offset. CONSTITUTION:A selection section 4 is switched so that study data being input data of a storage section 3 are inputted to a conversion section 1 and an error between the data converted by the conversion section 1 and study output data from the storage section 3 is obtained by a subtractor 5. Then, each weight and each offset are slightly changed by using the method of steepest descent so that the square error decreases based on the error. In this case, the neural network is structured to be three blocks with respect to an output color signal and an intermediate layer neuron 11h is coupled with only an output layer neuron 11o. Thus, the coupling between final output data and the neuron 11h is strengthened and the coupling with the other neuron 110 is weakened. Thus, the number of times of repetitive learning is reduced and the number of neuron components can be decreased.
