Abstract

The embodiment of the invention belongs to the field of artificial intelligence, and relates to a system strategy prediction method based on Granger causality, comprising: collecting related parameters and industrial data, the related parameters comprising at least one module variable of at least one system module, and the industrial data being historical data of each module variable; based on the historical data, performing causal analysis on each module variable by adopting a Granger causal relationship analysis mode based on an attention mechanism to obtain Granger causal strength between the historical data of each module variable and the current data; constructing a graph data structure to describe a system topological structure of the industrial system; and inputting the constructed graph data structure into the prediction model to obtain a prediction result of the system strategy. By adopting the method, the model prediction accuracy is improved.

Description

technical field [0001] The present application relates to the field of artificial intelligence, in particular to a system strategy prediction method, device, computer equipment and storage medium based on Granger causality. Background technique [0002] With the development of computer technology and the application of advanced control systems, the equipment and structure of modern industrial systems are becoming more and more complex, and industrial processes have accumulated a large amount of historical data, which includes the operating rules of the process, operator experience, product quality and process problems. and other rich information. How to obtain useful information from the data and provide a basis for the control and decision-making of the production process when it is difficult to establish an accurate mechanism model has become an issue of widespread concern to researchers and industries. Time series prediction based on industrial data is to use a large amo...
