摘要： A neural network device according to an embodiment includes an arithmetic circuit, a learning control circuit, and a bias reset circuit. The arithmetic circuit executes arithmetic processing according to a neural network using a plurality of weights each represented by a value of a first resolution and a plurality of biases each represented by a value in ternary. At the time of learning of the neural network, the learning control circuit repeats a learning process of updating each of the plurality of weights and each of the plurality of biases a plurality of times based on a result of the arithmetic processing according to the neural network performed by the arithmetic circuit. In each learning process, the bias reset circuit resets a bias randomly selected with a preset first probability among the plurality of biases to a median in the ternary.

摘要： According to an embodiment, an inference system includes a recurrent neural network circuit, an inference neural network, and a control circuit. The recurrent neural network circuit receives M input signals and outputs N intermediate signals, where M is an integer of 2 or more and N is an integer of 2 or more. The inference neural network circuit receives the N intermediate signals and outputs L output signals, where L is an integer of 2 or more. The control circuit adjusts a plurality of coefficients that are set to the recurrent neural network circuit and adjusts a plurality of coefficients that are set to the inference neural network circuit. The control circuit adjusts the coefficients set to the recurrent neural network circuit according to a total delay time period from timing for applying the M input signals until timing for firing the L output signals.
