Abstract

In this research, we explore the application of artificial neural networks, specifically the vector-quantized temporal associative memory (VQTAM) and VQTAM coupled with locally linear embedding (VQTAM-LLE) techniques, for simulating 2-D magnetotelluric forward modeling. The study introduces the concepts of VQTAM and VQTAM-LLE in the context of simulating 2-D magnetotelluric responses, outlining their underlying principles. We rigorously evaluate the accuracy and efficiency of both VQTAM variants through extensive numerical experiments conducted on diverse benchmark resistivity and real-terrain models. The results demonstrate the remarkable capability of VQTAM and VQTAM-LLE in accurately and efficiently predicting apparent resistivity and impedance phases, surpassing the performance of traditional numerical methods. This study underscores the potential of VQTAM and VQTAM-LLE as valuable computational alternatives for simulating magnetotelluric responses, offering a viable choice alongside conventional methods.

利用基于矢量量化时间关联记忆人工神经网络的方法模拟二维磁突触响应
在这项研究中,我们探索了人工神经网络,特别是向量量化时间关联记忆(VQTAM)和向量量化时间关联记忆与局部线性嵌入(VQTAM-LLE)技术在模拟二维磁突触前向建模中的应用。本研究在模拟二维磁突触响应的背景下介绍了 VQTAM 和 VQTAM-LLE 的概念,概述了它们的基本原理。我们通过在各种基准电阻率和真实地形模型上进行广泛的数值实验,严格评估了 VQTAM 两种变体的精度和效率。结果表明,VQTAM 和 VQTAM-LLE 在准确高效地预测表观电阻率和阻抗相方面具有卓越的能力,超越了传统数值方法的性能。这项研究强调了 VQTAM 和 VQTAM-LLE 作为模拟磁突触响应的重要计算替代方法的潜力,为传统方法提供了可行的选择。
