Title: Backpropagation neural network learning method with adaptive learning rates based on mean square deviation analysis
Inventor: PARK POO GYEON
IPC: G06N3/08
Filed: 2020-09-11
Abstract: The present invention relates to a back propagation neural network learning method having adaptive learning rates based on mean square deviation analysis. The learning rate is adaptively updated, depending on real-time errors to minimize a weight error by introducing a novel concept in which a back propagation error signal of an inner neural network at each layer is made by the weight error in a relevant layer. To this end, the present invention includes a first process and a second process to construct the back propagation neural network enhanced in impact noise or erroneously learning data. The first process is to establish a hypothesis that a back propagation error present in a j-th neuron of an n-th layer, which is essentially derived from a neural network algorithm, may be caused by the error of a weight connected between (n-1)-th and n-th layers, The second processor is to analyze a mean square deviation of a weight between the (n-1)-th layer and an n-th layer at the present time and updating the adaptive learning rate of a current time to minimize the mean square deviation of weights based on the analysis result.
