Data Analytics and AI

Abstract

Data analytics and artificial intelligence (AI) are transforming geotechnical monitoring by extracting insights from large sensor datasets. This chapter covers analytics objectives (trend detection, anomaly identification, and prediction) and data types (time-series, spatial, imagery, and point clouds). We discuss preprocessing: cleaning, labeling, and metadata standards. Exploratory analysis and visualization techniques are highlighted. Statistical methods (trend tests, change-point detection) and uncertainty quantification are reviewed. Time-series tools include filtering, smoothing, ARIMA, and Kalman filters (with equations). We survey anomaly detection approaches: simple thresholds, statistical tests, and unsupervised ML (clustering, PCA/autoencoders). Supervised learning for classification/regression (feature selection, model validation, and metrics like ROC/AUC) is covered. Deep learning methods (LSTMs/RNNs for sequences, CNNs/Transformers for images, PointNets for clouds) and physics-informed neural networks are introduced. Digital twins and the integration of ML with geomechanical models are discussed. Real-time analytics, streaming, and edge inference (MLOps) are addressed, as are alarm logic, false-positive management, and human-in-the-loop frameworks. We emphasize explainability, model validation, and regulatory guidance. Two worked examples illustrate a Kalman filter update and an ROC curve calculation. Tables compare algorithms (data needs, latency, interpretability), and a mermaid diagram shows an analytics pipeline. Case studies (slope failure warning, tailings instability, digital twin of a mine) demonstrate real-world AI use. Checklists (data preparation, model deployment) and a full References section are provided. AI’s promise in geotechnics is “step-change” improvements in efficiency and safety.
