Abstract(in English) | Loss of trailing digits in training deep convolutional neural network (DCNN) is considered to implement training with a format shorter than 16-bit floating format. As a result, we propose an 8-bit training method. The method improves inference accuracy compared to 16-bit floating format in training AlexNet. Simultaneously, the hardware size is reduced by half compared to the 16-bit hardware. |
