Deep Learning in Geotechnical Engineering: A Critical Assessment
Analysis
Key Takeaways
- •Deep learning methods like PINNs and DeepONet are often significantly slower and less accurate than traditional solvers for geotechnical problems.
- •Extrapolation beyond the training data envelope is a major challenge for these methods.
- •Automatic differentiation through traditional solvers is recommended for inverse problems.
- •Site-based cross-validation is crucial to account for spatial autocorrelation.
- •Neural networks should be reserved for problems where traditional solvers are genuinely expensive and predictions remain within the training envelope.
“PINNs run 90,000 times slower than finite difference with larger errors.”
