Abstract
A method and apparatus of accelerating deep learning, and a deep neural network are provided. The method comprises: randomly initializing weights and biases of a deep neural network as n-bit fixed-point numbers; reducing data in a plurality of layers in the deep neural network that have calculation amounts are greater than a first predetermined threshold as m-bit fixed-point numbers, where m and n are integers and m<n, and maintaining data in remaining layers among the plurality of layers as n-bit fixed-point numbers; and training the deep neural network after the reducing, until convergence.
