The identification and characterization of rock types is a core activity in geology and related fields, including mining, petroleum, environmental science, industry, and construction. Traditionally, this task is performed by human specialists who analyze and describe the type, composition, texture, shape, and other properties of rock samples, whether collected in-situ or prepared in a laboratory. However, the process is subjective, dependent on the specialist’s experience, and time-consuming. This study proposes an artificial intelligence-based approach that combines computer vision and natural language processing to generate both textual and verbal descriptions from images of rock thin sections. A dataset of images and corresponding textual descriptions is used to train a hybrid deep learning model. Features extracted from the images using EfficientNetB7 are processed by a Transformer network to generate textual descriptions, which are then converted into verbal responses using a speech synthesis service. The experimental results show an accuracy of 0.892 and a BLEU score of 0.71. This model offers potential utility for research, professional, and academic applications and has been deployed as a web application for public use.
岩石类型的识别和表征是地质和相关领域的核心活动,包括采矿、石油、环境科学、工业和建筑。传统上,这项任务是由人类专家来完成的,他们分析和描述岩石样品的类型、成分、质地、形状和其他特性,无论是在现场收集还是在实验室制备。然而,这个过程是主观的,取决于专家的经验,而且很耗时。本研究提出了一种基于人工智能的方法,将计算机视觉和自然语言处理相结合,从岩石薄片图像中生成文本和口头描述。使用图像和相应文本描述的数据集来训练混合深度学习模型。使用effentnetb7从图像中提取的特征由Transformer网络处理以生成文本描述,然后使用语音合成服务将其转换为口头响应。实验结果表明,该方法的准确率为0.892,BLEU分数为0.71。该模型为研究、专业和学术应用程序提供了潜在的实用程序,并已作为公共使用的web应用程序部署。

Geotechnical parameters derived from an intrusive cone penetration test (CPT) are used to asses mechanical properties to inform the design phase of infrastructure projects. However, local, in situ 1D measurements can fail to capture 3D subsurface variations, which could mean less than optimal design decisions for foundation engineering. By coupling the localised measurements from CPTs with more global 3D measurements derived from geophysical methods, a higher fidelity 3D overview of the subsurface can be obtained. Machine Learning (ML) may offer an effective means to capture all types of geophysical information associated with CPT data at a site scale to build a 2D or 3D ground model. In this paper, we present an ML approach to build a 3D ground model of cone resistance and sleeve friction by combining several CPT measurements with Multichannel Analysis of Surface Waves (MASW) and Electrical Resistivity Tomography (ERT) data on a land site characterisation project in the United Arab Emirates (UAE). To avoid a potential overfitting problem inherent to the use of machine learning and a lack of data at certain locations, we explore the possibility of using a prior Geo-Statistical (GS) approach that attempts to constrain the overfitting process by “artificially” increasing the amount of input data. A sensitivity study is also performed on input features used to train the ML algorithm to better define the optimal combination of input features for the prediction. Our results showed that ERT data were not useful in capturing 3D variations of geotechnical properties compared to Vs due to the geographical location of the site (200 m east from the Oman Gulf) and the possible effect of saline water intrusion. Additionally, we demonstrate that the use of a prior GS phase could be a promising and interesting means to make the prediction of ground properties more robust, especially for this specific case study described in this paper. Looking ahead, better representation of the subsurface can lead to a number of benefits for stakeholders involved in developing assets. Better ground/geotechnical models mean better site calibration of design methods and fewer design assumptions for reliability-based design, creating an opportunity for value engineering in the form of lighter construction without compromising safety, shorter construction timelines, and reduced resource requirements.
从侵入式锥体穿透测试(CPT)中获得的岩土参数用于评估机械性能,为基础设施项目的设计阶段提供信息。然而,局部的原位1D测量可能无法捕获三维地下变化,这可能意味着基础工程的最佳设计决策不足。通过将来自cpt的局部测量与来自地球物理方法的更多全局3D测量相结合,可以获得更高保真度的地下3D概况。机器学习(ML)可以提供一种有效的方法,在现场尺度上捕获与CPT数据相关的所有类型的地球物理信息,以建立2D或3D地面模型。在本文中,我们提出了一种ML方法,通过将多个CPT测量结果与多通道表面波分析(MASW)和电阻率层析成像(ERT)数据相结合,在阿拉伯联合酋长国(UAE)的一个地块特征描述项目中建立锥体阻力和套筒摩擦的三维地面模型。为了避免使用机器学习和某些位置缺乏数据所固有的潜在过拟合问题,我们探索了使用先前地理统计学(GS)方法的可能性,该方法试图通过“人为”增加输入数据量来限制过拟合过程。对用于训练ML算法的输入特征进行敏感性研究,以更好地定义用于预测的输入特征的最佳组合。我们的研究结果表明,由于场地的地理位置(距阿曼湾以东200米)和盐水入侵的可能影响,与v相比,ERT数据在捕获岩土力学特性的三维变化方面并不有用。此外,我们证明,使用先前的GS相位可能是一种有前途和有趣的方法,可以使地面性质的预测更加可靠,特别是对于本文中描述的具体案例研究。展望未来,更好地代表地下资源可以为参与开发资产的利益相关者带来许多好处。更好的地面/岩土模型意味着更好的现场校准设计方法和更少的基于可靠性设计的设计假设,以更轻的结构形式创造价值工程的机会,而不影响安全,更短的施工时间,减少资源需求。

Liquefaction is one of the prominent factors leading to damage to soil and structures. In this study, the relationship between liquefaction potential and soil parameters is determined by applying feature importance methods to Random Forest (RF), Logistic Regression (LR), Multilayer Perceptron (MLP), Support Vector Machine (SVM) and eXtreme Gradient Boosting (XGBoost) algorithms. Feature importance methods consist of permutation and Shapley Additive exPlanations (SHAP) importances along with the used model's built-in feature importance method if it exists. These suggested approaches incorporate an extensive dataset of geotechnical parameters, historical liquefaction events, and soil properties. The feature set comprises 18 parameters that are gathered from 161 field cases. Algorithms are used to determine the optimum performance feature set. Compared to other approaches, the study assesses how well these algorithms predict soil liquefaction potential. Early findings show that the algorithms perform well, demonstrating their capacity to identify non-linear connections and improve prediction accuracy. Among the feature set, σ,v (psf), MSF, CSRσ, v, FC%, Vs∗,40f t(f ps) and N1,60,CS are the ones that have the highest deterministic power on the result. The study's contribution is that, in the absence of extensive data for liquefaction assessment, the proposed method estimates the liquefaction potential using five parameters with promising accuracy.
液化是导致土壤和结构破坏的重要因素之一。在本研究中,通过将特征重要性方法应用于随机森林(RF)、逻辑回归(LR)、多层感知器(MLP)、支持向量机(SVM)和极端梯度增强(XGBoost)算法来确定液化势与土壤参数之间的关系。特征重要性方法包括置换和Shapley加性解释(SHAP)重要性,以及使用的模型内置的特征重要性方法(如果存在)。这些建议的方法包括岩土参数,历史液化事件和土壤特性的广泛数据集。该特性集包括从161个现场案例中收集的18个参数。采用算法确定最优性能特征集。与其他方法相比,该研究评估了这些算法预测土壤液化潜力的能力。早期的研究结果表明,这些算法表现良好,证明了它们识别非线性连接和提高预测精度的能力。在特征集中,σ,v (psf), MSF, CSRσ, v, FC%, Vs∗,40f t(f ps)和N1,60,CS对结果具有最高的确定性。该研究的贡献在于,在缺乏液化评估的大量数据的情况下,所提出的方法使用五个参数来估计液化潜力,具有很好的准确性。

Seismic data denoising is a critical process usually applied at various stages of the seismic processing workflow, as our ability to mitigate noise in seismic data affects the quality of our subsequent analyses. However, finding an optimal balance between preserving seismic signals and effectively reducing seismic noise presents a substantial challenge. In this study, we introduce a multi-stage deep learning model, trained in a self-supervised manner, designed specifically to suppress seismic noise while minimizing signal leakage. This model operates as a patch-based approach, extracting overlapping patches from the noisy data and converting them into 1D vectors for input. It consists of two identical sub-networks, each configured differently. Inspired by the transformer architecture, each sub-network features an embedded block that comprises two fully connected layers, which are utilized for feature extraction from the input patches. After reshaping, a multi-head attention module enhances the model’s focus on significant features by assigning higher attention weights to them. The key difference between the two sub-networks lies in the number of neurons within their fully connected layers. The first sub-network serves as a strong denoiser with a small number of neurons, effectively attenuating seismic noise; in contrast, the second sub-network functions as a signal-add-back model, using a larger number of neurons to retrieve some of the signal that was not preserved in the output of the first sub-network. The proposed model produces two outputs, each corresponding to one of the sub-networks, and both sub-networks are optimized simultaneously using the noisy data as the label for both outputs. Evaluations conducted on both synthetic and field data demonstrate the model’s effectiveness in suppressing seismic noise with minimal signal leakage, outperforming some benchmark methods.
地震数据去噪是一个关键的过程,通常应用于地震处理工作流程的各个阶段,因为我们减轻地震数据噪声的能力会影响我们后续分析的质量。然而,在保留地震信号和有效降低地震噪声之间找到最佳平衡是一个巨大的挑战。在本研究中,我们引入了一种多阶段深度学习模型,该模型以自监督的方式进行训练,专门用于抑制地震噪声,同时最大限度地减少信号泄漏。该模型是一种基于patch的方法,从噪声数据中提取重叠的patch,并将其转换为1D矢量进行输入。它由两个相同的子网组成,每个子网的配置不同。受变压器架构的启发,每个子网络都有一个嵌入式块,该块由两个完全连接的层组成,用于从输入补丁中提取特征。在重塑后,多头注意模块通过分配更高的注意权重来增强模型对重要特征的关注。这两个子网络的关键区别在于它们完全连接层中的神经元数量。第一个子网络作为强去噪器,神经元数量少,能有效地衰减地震噪声;相比之下,第二个子网络作为一个信号加回模型,使用更多的神经元来检索一些在第一个子网络的输出中没有保留的信号。所提出的模型产生两个输出,每个输出对应于一个子网络,并且两个子网络同时使用噪声数据作为两个输出的标签进行优化。对合成数据和现场数据的评估表明,该模型在以最小的信号泄漏抑制地震噪声方面是有效的,优于一些基准方法。

This study examines the stability of three-dimensional rectangular tunnel headings in drained c-ϕ soils, incorporating surcharge effects using 3D Finite Element Limit Analysis (FELA). It focuses on the upper and lower bound solutions for three stability factors: cohesion, surcharge, and soil unit weight (Nc, Ns, and Nγ). Based on Terzaghi's principle of superposition, the analysis evaluates tunnel stability under varying parameters, such as cover-depth ratio (H/D), width-depth ratio (B/D), and friction angle (ϕ). The results align closely with previous studies, and practical design charts are provided for calculating minimum support pressures. Additionally, machine learning models (ANN and XGBoost) are used to develop accurate correlations between input parameters and stability results. A relative importance index analysis is conducted to assess the impact of these parameters. This research enhances understanding of tunnel stability and offers practical insights for tunnel design.

This paper proposed a moment tensor regression prediction technology based on ResNet for microseismic events. Taking the great advantages of deep networks in classification and regression tasks, it can realize the great potential of fast and accurate inversion of microseismic moment tensors after the network trained. This ResNet-based moment tensor prediction technology, whose input is raw recordings, does not require the extraction of data features in advance. First, we tested the network using synthetic data and performed a quantitative assessment of the errors. The results demonstrate that the network exhibits high accuracy and efficiency during the prediction phase. Next, we tested the network using real microseismic data and compared the results with those from traditional inversion methods. The error in the results was relatively small compared to traditional methods. However, the network operates more efficiently without requiring manual intervention, making it highly valuable for near-real-time monitoring applications.

Deep learning based identification of rock minerals from un-processed digital microscopic images of undisturbed broken-surfaces 基于深度学习的岩石矿物识别,从未受干扰的破碎表面的未处理的数字显微图像
Pub Date : 2025-06-01 Epub Date: 2025-06-06 DOI: 10.1016/j.aiig.2025.100127

This study employed convolutional neural networks (CNNs) for the classification of rock minerals based on 3179 RGB-scale original microstructural images of undisturbed broken surfaces. The image dataset covers 40 distinct rock mineral-types. Three CNN architectures (Simple model, SqueezeNet, and Xception) were evaluated to compare their performance and feature extraction capabilities. Gradient-weighted Class Activation Mapping (Grad-CAM) was employed to visualize the features influencing model predictions, providing insights into how each model distinguishes between mineral classes. Key discriminative attributes included texture, grain size, pattern, and color variations.

本研究基于3179张rgb尺度原始破碎面显微结构图像,采用卷积神经网络(cnn)对岩石矿物进行分类。图像数据集涵盖了40种不同的岩石矿物类型。我们评估了三种CNN架构(Simple model、SqueezeNet和Xception),比较了它们的性能和特征提取能力。梯度加权类激活映射(Grad-CAM)用于可视化影响模型预测的特征,提供每个模型如何区分矿物类别的见解。关键的鉴别属性包括纹理、粒度、图案和颜色变化。纹理和晶界被认为是最关键的特征,因为它们是被最佳模型强烈激活的区域。带状和彩色对比等模式进一步提高了分类的准确性。性能分析表明,Simple模型隔离细粒度细节的能力有限,产生广泛而不太特定的激活(测试精度为0.84)。SqueezeNet在判别特征的定位上得到了改进,但偶尔会遗漏更精细的纹理细节(测试精度为0.95)。Xception模型优于其他模型,通过展示精确和紧密聚焦的激活,捕获复杂的纹理和微妙的颜色变化,实现了最高的分类精度(0.98测试精度)。其优越的性能可归因于其深层架构和高效的深度可分离卷积,这使得分层和详细的特征提取成为可能。结果强调了纹理、图案和颜色特征在准确矿物分类中的重要性,并强调了像Xception这样的深层、高效架构对此类任务的适用性。这些发现证明了cnn在地球科学研究中的潜力,为工业和科学应用中的自动矿物识别提供了一个框架。

Physics-informed neural networks (PINNs) are promising to replace conventional mesh-based partial differential equation (PDE) solvers by offering more accurate and flexible PDE solutions. However, PINNs are hampered by the relatively slow convergence and the need to perform additional, potentially expensive training for new PDE parameters. To solve this limitation, we introduce LatentPINN, a framework that utilizes latent representations of the PDE parameters as additional (to the coordinates) inputs into PINNs and allows for training over the distribution of these parameters. Motivated by the recent progress on generative models, we promote using latent diffusion models to learn compressed latent representations of the distribution of PDE parameters as they act as input parameters for NN functional solutions. We use a two-stage training scheme in which, in the first stage, we learn the latent representations for the distribution of PDE parameters. In the second stage, we train a physics-informed neural network over inputs given by randomly drawn samples from the coordinate space within the solution domain and samples from the learned latent representation of the PDE parameters. Considering their importance in capturing evolving interfaces and fronts in various fields, we test the approach on a class of level set equations given, for example, by the nonlinear Eikonal equation. We share results corresponding to three Eikonal parameters (velocity models) sets. The proposed method performs well on new phase velocity models without the need for any additional training.
基于物理信息的神经网络(pinn)有望通过提供更准确、更灵活的偏微分方程(PDE)解决方案,取代传统的基于网格的偏微分方程(PDE)求解器。然而,pinn的收敛速度相对较慢,并且需要对新的PDE参数进行额外的、可能昂贵的训练,这阻碍了它的发展。为了解决这个限制,我们引入了LatentPINN,这是一个框架,它利用PDE参数的潜在表示作为pinn的附加(坐标)输入,并允许在这些参数的分布上进行训练。由于生成模型的最新进展,我们提倡使用潜在扩散模型来学习PDE参数分布的压缩潜在表示,因为它们作为神经网络函数解的输入参数。我们使用了一个两阶段的训练方案,在第一阶段,我们学习PDE参数分布的潜在表示。在第二阶段,我们通过从解域内的坐标空间随机抽取的样本和从学习到的PDE参数的潜在表示中抽取的样本给出的输入训练一个物理信息的神经网络。考虑到它们在捕捉各个领域中不断变化的界面和前沿方面的重要性,我们在一类给定的水平集方程上测试了该方法,例如,由非线性Eikonal方程给出的水平集方程。我们共享了对应于三个Eikonal参数(速度模型)集的结果。该方法在新的相速度模型上表现良好,无需额外的训练。

Microseismic monitoring is essential for understanding subsurface dynamics and optimizing oil and gas production. However, traditional methods for the automatic detection of microseismic events rely heavily on characteristic functions and human intervention, often resulting in suboptimal performance when dealing with complex and noisy data. In this study, we propose a novel approach that leverages deep learning frame to extract multiscale features from microseismic data using a TransUNet neural network. Our model integrates the advantages of Transformer and UNet architectures to achieve high accuracy in multivariate image segmentation and precise picking of P-wave and S-wave first arrivals simultaneously. We validate our approach using both synthetic and field microseismic datasets recorded from gas storage monitoring and roof fracturing in a coal seam. The robustness of the proposed method has been verified in the testing of synthetic data with various levels of Gaussian and real background noises extracted from field data. The comparisons of the proposed method with UNet and SwinUNet in terms of the model architecture and classification performance demonstrate the TransUNet achieves the optimal balance in its architecture and inference speed. With relatively low inference time and network complexity, it operates effectively in high-precision microseismic phase pickings. This advancement holds significant promise for enhancing microseismic monitoring technology in hydraulic fracturing and reservoir monitoring applications.
微地震监测对于了解地下动态和优化油气生产至关重要。然而,传统的微地震事件自动检测方法严重依赖特征函数和人为干预,在处理复杂和有噪声的数据时,往往导致性能不佳。在这项研究中,我们提出了一种新的方法,利用深度学习框架,利用TransUNet神经网络从微地震数据中提取多尺度特征。我们的模型融合了Transformer和UNet架构的优点,实现了高精度的多变量图像分割和同时精确提取p波和s波首到达。我们利用煤层气储气库监测和顶板压裂记录的合成和现场微地震数据集验证了我们的方法。该方法的鲁棒性已在不同高斯噪声和真实背景噪声的合成数据测试中得到验证。通过与UNet和SwinUNet在模型结构和分类性能上的比较,表明TransUNet在模型结构和推理速度上达到了最佳平衡。该方法具有较低的推理时间和较低的网络复杂度,能够有效地进行高精度微震相位采集。这一进展为加强微地震监测技术在水力压裂和储层监测中的应用带来了重大希望。
