Addressing Seismic Data Imbalance with Novel AI
Problem: Traditional earthquake prediction models struggle with uneven data samples, particularly the scarcity of data for large earthquakes (magnitude 4.5+). This imbalance leads to models being skewed and reducing predictive power for critical events.
Solution: The Transformer-DCA model fuses the Transformer's sequence feature extraction capabilities with the Dendritic Cell Algorithm's (DCA) small-sample processing strength. This hybrid approach efficiently processes AETA multi-component monitoring data.
Impact: The model significantly improves earthquake prediction reliability, achieving better accuracy and recall compared to traditional methods like GBDT, SVM, and LSTM. It specifically boosts recall rates from 0.9065 to 0.9375, demonstrating robust generalization performance even with limited large-earthquake data.
