Classification: CPC G | IPC G

Claim 18:
19. The method of claim 12, wherein:
the error propagation procedure is configured to, when the error occurs in the N-th layer in response to initiation of training of the deep neural network, determine an error propagation value for a first layer to be a first error propagation value based on the error occurring in the N-th layer and then directly propagate the first error propagation value to the first layer,
the weight gradient update procedure is configured to update a forward weight (W1) for the first layer based on both a feed-forward value input to the first layer and the first error propagation value in response to transfer of the first error propagation value, and
the feed-forward procedure is configured to, when update of the forward weight (W1) is completed, perform a feed-forward operation on a new input value in the first layer using the forward weight (W1).
