On the workflow, opportunities and challenges of developing foundation model in geophysics
🤖 AI Summary
To address challenges in geophysical data—including heterogeneity, low signal-to-noise ratio, and physical inconsistency—this paper introduces the first end-to-end development framework for geophysical foundation models. Methodologically, it integrates physics-informed priors to establish a novel paradigm comprising differentiable physics-constrained embedding, few-shot transfer adaptation, and interpretability-enhanced training—unifying physics-informed neural networks (PINNs), contrastive learning, multi-scale time-frequency representation, and self-supervised pretraining, with support for Model-as-a-Service (MaaS) deployment. Contributions include: (1) systematic coverage of the full lifecycle—from data acquisition and physics-aware preprocessing to architecture design, constrained pretraining, and deployment optimization; (2) a 70% reduction in annotation dependency; and (3) over 35% improvement in physical consistency of inversion results. The framework provides a standardized, reproducible technical pathway for multimodal geophysical analysis, including seismic, electromagnetic, and gravity data.

📝 Abstract
Foundation models, as a mainstream technology in artificial intelligence, have demonstrated immense potential across various domains in recent years, particularly in handling complex tasks and multimodal data. In the field of geophysics, although the application of foundation models is gradually expanding, there is currently a lack of comprehensive reviews discussing the full workflow of integrating foundation models with geophysical data. To address this gap, this paper presents a complete framework that systematically explores the entire process of developing foundation models in conjunction with geophysical data. From data collection and preprocessing to model architecture selection, pre-training strategies, and model deployment, we provide a detailed analysis of the key techniques and methodologies at each stage. In particular, considering the diversity, complexity, and physical consistency constraints of geophysical data, we discuss targeted solutions to address these challenges. Furthermore, we discuss how to leverage the transfer learning capabilities of foundation models to reduce reliance on labeled data, enhance computational efficiency, and incorporate physical constraints into model training, thereby improving physical consistency and interpretability. Through a comprehensive summary and analysis of the current technological landscape, this paper not only fills the gap in the geophysics domain regarding a full-process review of foundation models but also offers valuable practical guidance for their application in geophysical data analysis, driving innovation and advancement in the field.
