Abstract

The invention discloses a mobile edge distributed machine learning system and method. In the method, D2D communication technology is used to unload data samples between terminal devices, and by adjusting the number of data samples stored by terminal devices participating in distributed machine learning, each terminal The data sample size of the device matches its computing power, which balances the time consumed by the computing and communication of each terminal device, and solves the problem of low efficiency of distributed machine learning model training caused by the large difference in computing and communication capabilities of different terminal devices. It can reduce the impact of data non-independent and identical distribution characteristics on model accuracy.

Description

technical field [0001] The present invention relates to the technical field of edge intelligence applications, in particular to a mobile edge distributed machine learning system and method. Background technique [0002] With the rapid development of the Internet of Things and artificial intelligence, network edge intelligence is an inevitable development trend. Distributed machine learning (distributed machine learning) is one of the important research directions, which effectively combines artificial intelligence (AI) and mobile edge computing (mobile edge computing, MEC) technology, at the edge of the network, through the joint edge server and Mass computing and terminal devices with limited communication capabilities realize distributed machine learning. Distributed machine learning can be divided into two training modes: synchronous and asynchronous. Since the asynchronous training mode has serious gradient failure problems, many research works are based on distributed ...
