用生成对抗网络生成基于物理测量的真实地质

Generating Realistic Geology Conditioned on Physical Measurements with Generative Adversarial Networks

摘要:

地质统计学中的一个重要问题是在稀疏的空间位置建立给定物理测量的地球地下模型。通常,这是使用空间插值方法或通过从参考图像再现图案来完成的。然而,这些算法不能产生现实的模式,并没有表现出广泛的不确定性,在地质预测固有的。在本文中,我们展示了如何使用生成对抗网络的语义修复来生成各种地质学实现,这些实现在匹配预期地质模式的同时尊重物理测量。与其他算法相比,我们的方法可以很好地扩展数据点的数量,并模仿模式的分布,而不是单一的模式或图像。生成的条件样本是最先进的。

英文摘要:

An important problem in geostatistics is to build models of the subsurface of the Earth given physical measurements at sparse spatial locations. Typically, this is done using spatial interpolation methods or by reproducing patterns from a reference image. However, these algorithms fail to produce realistic patterns and do not exhibit the wide range of uncertainty inherent in the prediction of geology. In this paper, we show how semantic inpainting with Generative Adversarial Networks can be used to generate varied realizations of geology which honor physical measurements while matching the expected geological patterns. In contrast to other algorithms, our method scales well with the number of data points and mimics a distribution of patterns as opposed to a single pattern or image. The generated conditional samples are state of the art.
