ABSTRACT:
A multilayered optical neural network system comprise an input layer, an output layer, at least one hidden layer provided between the input layer and the output layer, a memory matrix holding device provided between the respective layers for holding weighted couplings between the layers, a correlation operating device for optically computing a correlation between an output optical pattern from the previous layer and the memory matrix pattern, an output function operating device for implementing optical computing of an output function corresponding to a result of the correlation operation, and a memory matrix correcting device provided between the respective layers for optically correcting a memory matrix held in the memory matrix holding device by a learning operation, whereby the system is capable of two-dimensional optical computing of all data transfers and operations and executing a great amount of computing without use of holograms.
