AI Technical Summary

Technical Problem

Existing suspended solids concentration detection models lack generalization ability, making it difficult to cover deep water bodies. Sensor networks also face high data transmission pressure, hindering efficient real-time modeling.

Method used

A federated learning architecture combining all-weather remote sensing and underwater acoustic sensor networks is adopted. The global model is initialized through a central server, and the underwater acoustic sensor nodes perform local training and parameter uploading. The global model is then aggregated and updated. The CNN-LSTM-Attention model is used to extract underwater acoustic signal features and introduce remote sensing inversion labels to achieve distributed data collaborative modeling.

Benefits of technology

It improves the coverage and accuracy of detection, reduces data transmission latency and server load, and enhances the model's generalization ability and robustness.
