English(EN) Extending Occam's inversion with lasso fusion, overcomplete dictionaries, and isotropic total variation regularisation

地球物理学算法通过先进统计方法更新

研究人员通过结合 Lasso 融合和过完备字典,扩展了 Occam 反演(一种地球物理算法)。这种新方法旨在通过采用统计学和成像中常用的 l1 正则化技术来生成更清晰的模型。该研究详细介绍了三种求解器——坐标下降、迭代重加权最小二乘法 (IRLS) 和分裂 Bregman——的数学框架,并根据性能推荐了 1D 和 2D 问题的特定求解器。 AI

影响 这项研究将先进的统计和成像技术引入地球物理反演,有望产生更准确、更详细的地下模型。

    利用 Lasso 融合、过度完备字典和各向同性全变分正则化扩展奥卡姆逆演算法

    arXiv:2608.14225v1 Announce Type: new Abstract: Occam's inversion is a robust algorithm to perform nonlinear geophysical inversion. It provides the smoothest model within observation noise, thereby discouraging geological overinterpretation. While Occam originally penalised l2 mo…
