Abstract

The invention discloses a method, a system and a device for predicting cellular flow and medium. The method comprises the following steps: acquiring cellular flow data; carrying out feature extraction on the cellular flow data from a global space view angle, a global time view angle and a local space-time view angle in sequence; predicting cellular flow according to the extracted features; wherein an attention mechanism is adopted to obtain node-level global spatial correlation and trend-level global spatial correlation of different cellular flow units, and the global spatial correlation of the two levels is fused; acquiring global correlation of data of the same cellular flow unit at different historical moments by adopting an attention mechanism; after global space-time correlation capture is completed by adopting convolution operation,capturing local space-time correlation continuesely. The method comprehensively captures the space-time correlation of the cellular flow from a global space view angle, a global time view angle and a local space-time view angle, realizes complete modeling of the space-time characteristics of the cellular flow, and can be widely applied to the technical field of communication.
