Abstract

The application aims to provide a data processing method and device based on a neural network. The method comprises steps that precision conversion for single precision floating point type data of the neural network is carried out; neural network calculation for the low precision floating point type data after precision conversion is carried out. Compared with the prior art, the method and the device are advantaged in that solving a large storage content problem in a low precision mode is facilitated, the memory space occupied by a model can be saved, a larger model can operate through utilizing same hardware configuration, and the memory or hardware space occupied by a data set can be saved; when the model is deployed on a cluster, network bandwidth required during synchronization can be effectively reduced, communication cost can be effectively reduced, and integral performance is improved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a neural network-based data processing method and device. Background technique [0002] With the continuous upgrading of computer technology, neural networks have made great progress in simulating human intelligence. After decades of development, the current neural network is developing towards larger models and larger data sets. Using larger models and larger data sets can achieve higher classification and detection accuracy, but it brings problems. It is a substantial increase in the amount of calculation and storage. The problem of large amount of calculation can be solved by high-performance hardware such as multi-core CPU and GPU, using larger memory capacity, larger hard disk capacity, and faster network hardware to meet the increasing neural network parameters and data sets, but it is facing upgrades Long cycle, poor stability, excessive investment in equipment and oth...
