Journal ArticleDOI
An artificial neural network-based condition monitoring method for wind turbines, with application to the monitoring of the gearbox
TL;DR: An overview of the most important publications that discuss the application of ANN for condition monitoring in wind turbines and a method utilizing the Mahalanobis distance is presented, which improves the anomaly detection by considering the correlation between ANN model errors and the operating condition.
Journal ArticleDOI
A Sequential Pressure-Based Algorithm for Data-Driven Leakage Identification and Model-Based Localization in Water Distribution Networks
Ivo Daniel,Jorge E. Pesantez,Simon Letzgus,Mohammad Ali Khaksar Fasaee,Faisal Ali M Alghamdi,Emily Zechman Berglund,Gnanamanikam Mahinthakumar,Andrea Cominola +7 more
TL;DR: The leakage identification and localization algorithm (LILA) as discussed by the authors identifies potential leakages via semisupervised linear regression of pairwise sensor pressure data and provides the location of their nearest sensors.
Journal ArticleDOI
Change-point detection in wind turbine SCADA data for robust condition monitoring with normal behaviour models
TL;DR: An appropriate SCADA data preprocessing procedure is introduced to ensure their feasibility and conduct comprehensive comparisons across several hyperparameter choices, and the combination of Laplace kernels with a newly introduced bandwidth and regularisation-penalty selection heuristic robustly outperforms existing methods.
Journal ArticleDOI
Toward Explainable Artificial Intelligence for Regression Models: A methodological perspective
Simon Letzgus,Patrick Wagner,Jonas Lederer,Wojciech Samek,Klaus-Robert Müller,Grégoire Montavon +5 more
TL;DR: This review clarifies the fundamental conceptual differences of XAI for regression and classification tasks, establishes novel theoretical insights and analysis for XAIR, provides demonstrations of XAIR on genuine practical regression problems, and discusses challenges remaining for the field.
Journal ArticleDOI
A GIS-Based Planning Approach for Urban Power and Natural Gas Distribution Grids with Different Heat Pump Scenarios
TL;DR: In this article, a case study for a neighborhood energy model, the load profiles were assigned to buildings in an example town using public data on locations, building age and energetic refurbishment variants.
