Fig. 10From: A hybrid RNN-GPOD surrogate model for real-time settlement predictions in mechanised tunnellingComparison of GPOD and iterative GPOD methods (IGPOD) with FE results. Prediction of surface settlements in step 23. The GPOD, the IGPOD based upon the Everson–Sirovich(E–S) method and the Venturi–Karniadakis (V–K) method lead to an error of 5.18; 5.03 and 1.36 %, respectively (for validation case 1)Back to article page
