Description

technical field [0001] The present invention relates to the technical fields of deep learning, edge computing and distributed computing, and more specifically, to a multi-user deep neural network model segmentation and resource allocation optimization method in an edge computing scenario. Background technique [0002] With the gradual popularization of 5G technology and the continuous development of technologies such as mobile artificial intelligence and the Internet of Things (IoT for short), the number of devices at the edge of the network has ushered in explosive growth. At the same time, terminal devices at the edge of the network are gradually transitioning from the role of consumers of smart applications to special nodes that are both consumers and producers, and continue to generate massive amounts of real-time data during operation. However, the traditional mobile cloud computing method is limited by the transmission bandwidth of the backbone network and the high tra...

Problems solved by technology

[0004] The first idea is to optimize the model itself, which has the advantage of not requiring other additional equipment support, but it is also accompanied by several difficult problems: First, the accuracy of the model after compression is usually difficult to guarantee theoretically, and not all All models are suitable for compression; the second is that structure-based weight pruning cannot be applied to all models, and general weight pruning that is not based on structure wi
