DDPS - A Flexible and Generalizable XAI Framework for Scientific Deep Learning
Inside Livermore Lab via YouTube
Overview
Syllabus
Intro
Deep learning in physics-based systems
Scientific modeling in the age of Al
Lots of data BUT not enough!
Out-of-distribution (OOD) generalization
Interpretable and explainable Al (XAI)
Key idea: Integral equations!
Theory-guided machine learning
Functional data analysis (FDA)
Applications
Motivation example: 1D
Predicting strain energy from heterogeneous material property
Predicting velocity field from heterogeneous permeability
Summary: towards interpretable and generalizable deep learning
Acknowledgments
Example 3: Predicting high-fidelity wall shear stress (WSS) from low-fidelity velocity
Example 5: Local interpretation: Predicting velocity field from permeability fields
Appendix: Library
Generalized functional data analysis (gFDA)
