Efficient One-Step Surface-Wave Tomography through Implicit Differentiation and Jacobian Factorization
Yiran Jiang, Ping Tong, Jianwei Ma
Surface-wave tomography provides important constraints on the crust and upper mantle, but directly inverting millions of measurements for three-dimensional structure remains comput…
Seismology modeling agent: A smart assistant for geophysical researchers
Yukun Ren, Siwei Yu, Kai Chen +1
To address the steep learning curve and reliance on complex manual file editing and command-line operations in the traditional workflow of the mainstream open-source seismic wave s…
Fractal Flow: Hierarchical and Interpretable Normalizing Flow via Topic Modeling and Recursive Strategy
Binhui Zhang, Jianwei Ma
Normalizing Flows provide a principled framework for high-dimensional density estimation and generative modeling by constructing invertible transformations with tractable Jacobian…
Feature-Space Planes Searcher: A Universal Domain Adaptation Framework for Interpretability and Computational Efficiency
Zhitong Cheng, Yiran Jiang, Yulong Ge +4
Domain shift, characterized by degraded model performance during transition from labeled source domains to unlabeled target domains, poses a persistent challenge for deploying deep…
Foundation Models for Geophysics: Review and Perspective
Qi Liu, Jianwei Ma
Recently, large models, or foundation models, have exhibited remarkable performance, profoundly impacting research paradigms in diverse domains. Foundation models, trained on exten…
