Hibrit Makine Öğrenmesi ve Derin Öğrenme Modelleri Kullanılarak Geliştirilmiş Deprem Büyüklüğü Tahmini

Öz

Bu çalışma, tarihsel sismik verileri kullanarak deprem büyüklüklerini tahmin etmek için makine öğrenimi ve hibrit derin öğrenme modellerinin performansını değerlendirmektedir. Rastgele Orman (RF), ARIMA, Uzun Kısa Dönem Bellek (LSTM), CNN+LSTM ve Transformatör + Gauss Süreçleri (GP) dahil olmak üzere beş model, Ortalama Karesel Hatanın Kökü (RMSE) ve R^2 gibi ölçütler kullanılarak karşılaştırılmıştır. RF modeli, 0,072 RMSE ve 0,30 R^2 ile oldukça verimliydi. Ancak, zamansal analizi içermiyordu. ARIMA da 0.065 RMSE ve 0.42 R^2 ile daha iyiydi ve doğrusal ilişkiler için en uygun modeldi. LSTM sıralı ilişkileri iyi tanımlamış ve 0.097 RMSE ve 0.51 R^2 sağlamıştır. Hibrit CNN+LSTM modeli, uzamsal ve zamansal özellikleri birleştirerek 0,090 RMSE ve 0,58 R^2 ile bağımsız yaklaşımlardan daha iyi performans göstermiştir. Transformatör + GP modeli, 0,063 RMSE ve 0,62 R^2 ile en yüksek doğruluğu elde etmiş ve güven aralıkları aracılığıyla sağlam belirsizlik ölçümü sunmuştur. Bu sonuçlar, sismik tahminde hibrit modellerin üstünlüğünü vurgulamakta, tahmin doğruluğunu artırma ve daha iyi risk yönetimi stratejilerini destekleme potansiyellerini göstermektedir.

Enhanced Earthquake Magnitude Prediction Using Hybrid Machine Learning and Deep Learning Models

Öz

This study evaluates the performance of machine learning and hybrid deep learning models for predicting earthquake magnitudes using historical seismic data. Five models, including Random Forest (RF), ARIMA, Long Short-Term Memory (LSTM), CNN+LSTM, and Transformer + Gaussian Processes (GP), were compared using metrics such as Root Mean Squared Error (RMSE) and R2. The RF model was quite efficient, with an RMSE of 0.072 and an R2 of 0.30. However, it did not incorporate temporal analysis. ARIMA was also better, with an RMSE of 0.065 and R2 of 0.42, which is best suited for linear relationships. LSTM identified the sequential relations well and provided an RMSE of 0.097 and R2 of 0.51. The hybrid CNN+LSTM model outperformed standalone approaches with an RMSE of 0.090 and R2 of 0.58 by combining spatial and temporal features. The Transformer + GP model achieved the highest accuracy, with an RMSE of 0.063 and R2 of 0.62, offering robust uncertainty quantification through confidence intervals. These results highlight the superiority of hybrid models in seismic forecasting, demonstrating their potential to improve predictive accuracy and support better risk management strategies.
