AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively analyze the pollutant transfer relationships across multiple media and stages, especially lacking quantitative means for indirect coupling effects across media and stages. Furthermore, traditional methods cannot adapt to the dynamic changes in causal relationships in complex systems, leading to unreliable verification results.

Method used

By preprocessing pollutant monitoring data, the main characteristic components representing the distribution and evolution of pollutants are extracted, a transmission coupling relationship model is constructed and jointly verified, including filling missing values ​​using a spatiotemporal attention graph convolutional network, dimensionality reduction based on manifold learning algorithm and principal component analysis, training the transmission coupling relationship model with graph attention neural network, establishing a causal network skeleton and performing dynamic verification.

Benefits of technology

It achieves the quantification, causation, spatialization, and dynamization of pollution source tracing in target areas, improving the accuracy and efficiency of pollution control. It can accurately simulate the transmission path and coupling strength of pollutants, ensuring the scientific validity and reliability of the source tracing results.
