Classification: G06N

Abstract:
A neural network circuit comprising:a) a training network comprising: (i) a plurality of analog circuits capable of charge storage; (ii) a plurality of analog transfer function circuits each being continuously coupled to at least one of the charge storage circuits; (iii) a plurality of analog derivative circuits each being continuously coupled to one of the plurality of transfer function circuits and constructed to continuously generate in real time a derivative of an output of the one transfer function circuit; and (iv) a weight update analog circuit for continuously updating the charge storage circuits based upon output from the plurality of transfer function circuits and output from the plurality of derivative circuits; and b) a validation network comprising: (i) a plurality of transfer function circuits each being coupled to the plurality of charge storage circuits so as to replicate the coupling of the plurality of charge storage-to-the plurality of transfer function circuits of the training network.
