English(EN) ROMNet: a hybrid reduced order modeling and machine learning approach to waveform inversion

新的ROMNet方法结合机器学习和降阶模型进行地震成像

研究人员开发了ROMNet,这是一种结合降阶模型(ROM)和机器学习以改进地震成像波形反演的新方法。该方法旨在通过使用神经网络更有效地将ROM矩阵映射到波速,来降低传统全波形反演(FWI)相关的计算成本和复杂性。ROMNet使用合成数据和GeoFWI数据集进行了测试,在与Fourier-DeepONet和InversionNet等其他基于深度学习的FWI技术相比时,表现具有竞争力。 AI

影响 这种混合方法可以加速地震数据处理,并提高用于地震分析和资源勘探等应用的地下成像精度。
