Parameter-Efficient Adaptation of Pre-Trained Vision Foundation Models for Active and Passive Seismic Data Denoising

- 用LoRA微调预训练视觉模型,仅新增少量参数即可适配地震任务。
- 在无标签数据下通过峭度引导自校准,实现跨站点噪声抑制。
- 在中美德三地数据上表现超越专用模型,通用性强。
高分辨率地下成像与持续地球监测推动了密集地震仪部署、分布式声学传感(DAS)阵列及大规模2D/3D调查中主动与被动地震数据的快速增长。这一增长使复杂噪声抑制愈发困难,尤其在需保持信号保真度的情况下。传统监督深度学习方法通常任务特定,依赖大量配对数据,且在新采集条件下易受领域偏移影响。基础模型提供可行替代方案,但从头预训练地震基础模型需海量领域数据和巨大算力。本文提出一种高效框架,通过参数高效微调将通用视觉基础模型(VFMs)应用于地球物理任务。架构采用预训练的DINOv3编码器,结合低秩适应(LoRA)实现少参数有效特征适配。为提升在未见野外条件下的鲁棒性,提出基于峭度引导的无监督测试时自适应模块,在推理阶段仅更新LoRA参数。该模块通过峭度识别信息丰富区域,进行无标签自训练,实现模型自校准。在公开勘探地震图像和犹他州FORGE站点的DAS垂直地震剖面数据上实验表明,该框架性能匹配或优于专用模型。在来自中国陆地调查与德国Groß Schönebeck地热站的跨站点未见数据测试中进一步验证其强泛化能力与有效的信号-噪声分离。结果凸显了将预训练视觉模型适配至勘探地震学等数据密集型问题的潜力。
原文摘要 · Abstract (English)
The demand for high-resolution subsurface imaging and continuous Earth monitoring has driven rapid growth in active and passive seismic data from dense geophone deployments, distributed acoustic sensing (DAS) arrays, and large-scale 2D and 3D surveys. This expansion makes complex noise suppression increasingly challenging, especially when signal fidelity must be preserved. Conventional supervised deep learning methods are often task-specific, require large paired datasets, and can suffer from domain shift under new acquisition conditions. Foundation models offer a promising alternative, but pre-training seismic foundation models from scratch requires massive domain-specific data and substantial computation. We propose an efficient framework that repurposes general-purpose Vision Foundation Models (VFMs) for geophysical tasks through Parameter-Efficient Fine-Tuning. The architecture uses a pre-trained VFM, a DINOv3 encoder, adapted with Low-Rank Adaptation (LoRA) to enable effective feature adaptation with few additional parameters. To improve robustness under unseen field conditions without ground truth, we introduce a kurtosis-guided unsupervised test-time adaptation module that updates only LoRA parameters during inference. This module self-calibrates the model to site-specific noise by identifying information-rich regions via kurtosis and performing self-training without labeled data. Experiments on public exploration seismic images and DAS vertical seismic profiling data from the Utah FORGE site show that the framework matches or outperforms domain-specific models. Tests on unseen cross-site data from a land survey in China and the Groß Schönebeck geothermal site in Germany further demonstrate strong generalization and effective signal-noise separation. These results highlight the potential of adapting pre-trained VFMs to data-intensive problems in exploration seismology.
