Abstract

The present disclosure provides a neural network training device and a related product, the training device comprises X neural network chips, the X neural network chips being connected to each other,the value range of X being an integer greater than or equal to 2; wherein Y neural network chips in the X neural network chips are used for receiving neural network training data and executing training operation to obtain Y weight gradients, and Y is smaller than or equal to X; wherein Z neural network chips in the X neural network chips are used for receiving the weight gradients sent by the Y neural network chips and integrating the Y weight gradients into the trained final weight gradient according to a pre-strategy, and Z is smaller than or equal to X. The technical scheme provided by theinvention has the advantages of high training speed and short time consumption.

Description

technical field [0001] The present disclosure relates to the field of neural networks, in particular to a neural network training device and related products. Background technique [0002] Artificial Neural Network (ANN) is a research hotspot in the field of artificial intelligence since the 1980s. It abstracts the human brain neuron network from the perspective of information processing, establishes a simple model, and forms different networks according to different connection methods. In engineering and academia, it is often referred to directly as a neural network or a neural network. A neural network is an operational model consisting of a large number of nodes (or neurons) connected to each other. [0003] The calculation of the existing neural network is based on CPU (Central Processing Unit, central processing unit) or GPU (English: Graphics Processing Unit, graphics processing unit) to realize the calculation of neural network, and the training speed of a single tr...
