Problems solved by technology

[0004] Regarding the establishment of the land subsidence prediction model, the traditional method is usually to train the model in a stand-alone and serial mode. When faced with massive data, due to the huge amount of data, the storage and processing of data will expose poor fault tolerance, slow speed, low efficiency
This is contrary to the real-time, rapidity and accuracy required for shield ground subsidence prediction
At the same time, the amount of data used by traditional methods is small, which has a great impact on the accuracy of the established forecasting model
