This study evaluates unsupervised machine learning (ML) models for seismic facies mapping within the Barail group from the Amguri region of the Upper Assam basin in northeast (NE) India. Utilizing high-quality three-dimensional seismic data, a comprehensive set of seismic attributes, including amplitude-based, instantaneous, spectral, geometric, and textural measures, is extracted, optimally selected, and integrated using two unsupervised models: the self-organizing map (SOM) and the generative topographic mapping (GTM). The two models are compared to identify the most effective approach for discerning seismic facies patterns within the Barail-Coal-Shale (BCS) and Barail-Main-Sand (BMS) units. Results indicate that GTM outperforms SOM by providing improved cluster separation, enhanced facies continuity, and greater geological consistency across the target interval in the study area. GTM-derived facies insights are validated with borehole and field data, facilitating an in-depth interpretation of the sedimentary environment. The BCS interval predominantly consists of coaly shale, coal-shale alternations, and minor sandstone facies, indicative of a swampy deltaic setting conducive to periodic vegetation accumulation. In contrast, the BMS interval primarily comprises sandstone with occasional shale and coal-shale intercalations, reflecting a fluvial-dominated environment. Post-depositional tectonic processes contributed to the deformation and structural complexity within these intervals. The proposed methodology (specifically data enhancement, attribute optimization, ML model comparison and integration of interpretations with different geoscientific data) demonstrates potential for application in other geological settings to enhance subsurface interpretation.</div></div>","PeriodicalId":100124,"journal":{"name":"Artificial Intelligence in Geosciences","volume":"7 1","pages":"Article 100196"},"PeriodicalIF":4.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these limitations, this paper introduces a deep generative model-based parameterization that effectively reduces dimensionality, preserves non-Gaussian patterns, and enhances linearity with observational data. We propose a regularized variational autoencoder (RVAE) comprising three integrated components: (1) an encoder that projects high-dimensional reservoir model parameters into a low-dimensional latent space, capturing complex non-Gaussian distributions; (2) a decoder that maps latent variables back to the original model space, ensuring accurate and geologically consistent reconstruction; and (3) a lightweight linear subnetwork that imposes additional regularization on the latent space, enforcing a linear relationship with observational data. This RVAE framework strengthens ensemble-based methods by aligning the parameterization more closely with their linear-Gaussian assumptions, thereby enhancing compatibility and improving history matching accuracy. Given the high computational cost and time typically required for forward reservoir simulations, we adopt a semi-supervised learning approach, utilizing a dataset where only a small subset of the generated model realizations is paired with production data derived from these simulations. For the network design, the core architecture of the RVAE is based on a convolutional DenseNet, integrated with an attention mechanism to optimize feature representation. Experimental results demonstrate that the proposed approach effectively captures non-Gaussian patterns in permeability fields and significantly improves the assimilation of highly nonlinear production data.</div></div>","PeriodicalId":100124,"journal":{"name":"Artificial Intelligence in Geosciences","volume":"7 1","pages":"Article 100201"},"PeriodicalIF":4.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147396655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to automatically classify ground deformation processes in Spain using a machine learning approach applied to InSAR-based datasets. The database integrates InSAR measurement points (MPs) from 20 case studies in Spain, obtained from various institutional sources, and 32 geoenvironmental variables related to ground deformation, morphometry, geology, climate, and land use. The proposed classification strategy follows a hierarchical structure with two levels: first, distinguishing between landslides and subsidence; then, identifying the specific type within each main class (mining landslide, environmental landslide, constructive subsidence, mining subsidence, and piezometric subsidence). Several machine learning algorithms (Naïve Bayes, Logistic Regression, Decision Tree, Random Forest, Extra Trees, Gradient Boosting Machine, XGBoost, LightGBM, and CatBoost) and data configurations were tested, combining different spatial resolutions and class balancing techniques. The best performance (Cohen's Kappa = 0.78) was achieved with the hierarchical approach using the 200 m grid dataset, applying XGBoost for the parental and landslide models, and CatBoost for the subsidence model. Using this approach, 70 % de test sites achieved over 88 % correctly classified cells, 20 % had between 50 % and 83 %, and only one test case was entirely misclassified. The analysis of the most relevant variables indicates that annual mean precipitation, mining activity, buildings, landslide susceptibility, and slope are key factors. These results demonstrate the potential of the hierarchical approach to improve classification and lay the groundwork for future application at national and European scales, incorporating new training cases, process types, and continental data sources. In conclusion, this study presents, for the first time, a hierarchical machine learning model capable of accurately classifying ground deformation processes in Spain, with the aim of supporting territorial management and geohazard mitigation.</div></div>","PeriodicalId":100124,"journal":{"name":"Artificial Intelligence in Geosciences","volume":"7 1","pages":"Article 100171"},"PeriodicalIF":4.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145841219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unsupervised representation learning is a research area in Artificial Intelligence (AI) that lies at the core of this challenge, as this way of learning can create useful image representations by utilizing large volumes of data without requiring labels.

The proposed monitoring framework integrated spectral feature selection methods, data augmentation techniques with ensemble learning models, using multi-temporal multispectral imagery acquired by unmanned aerial vehicles (UAVs). Firstly, one two-stage Otsu adaptive thresholding method was utilized to efficiently extract rice pixels from UAV images captured at different growth stages, thereby eliminating non-rice noise in paddy field imagery. Subsequently, spectral vegetation indices, and texture features of rice UAV images were extracted. Three feature selection methods—GRA, mRMR, and SHAP—were employed to identify chlorophyll-sensitive features. Finally, based on Gaussian Mixture Model (GMM)-based data augmentation strategy and the selected sensitive features, one two-layer ensemble learning framework optimized by using Particle Swarm Optimization (PSO) algorithm was proposed to achieve accurate and efficient estimation of rice chlorophyll content across different growth stages. The results demonstrate that the SHAP-based feature selection method consistently achieved the best prediction performance across all growth stages, highlighting its superiority in retaining key feature information and enhancing model stability.
