Machine learning algorithms for damage detection: Kernel-based approaches
TL;DR: Four kernel-based algorithms for damage detection under varying operational and environmental conditions, namely based on one-class support vector machine, support vector data description, kernel principal components analysis and greedy kernel principal component analysis are presented.
Journal ArticleDOI
A novel unsupervised approach based on a genetic algorithm for structural damage detection in bridges
Moisés Silva,Adam Santos,Eloi Figueiredo,Reginaldo Santos,Claudomiro Sales,João C. W. A. Costa +5 more
TL;DR: A novel unsupervised and nonparametric genetic algorithm for decision boundary analysis (GADBA) to support the structural damage detection process, even in the presence of linear and nonlinear effects caused by operational and environmental variability is proposed.
Journal ArticleDOI
Multi-objective genetic algorithm for missing data imputation
Fábio Manoel França Lobato,Claudomiro Sales,Igor M. Araujo,Vincent Tadaiesky,Lilian de Nazaré Santos Dias,Leonardo Ramos,Ádamo Lima de Santana +6 more
TL;DR: This is the first method that applies a multi-objective approach to data imputation, based on the NSGA-II, which is suitable for mixed-attribute datasets and takes into account information from incomplete instances and the modeling task.
Journal ArticleDOI
Genetic-based EM algorithm to improve the robustness of Gaussian mixture models for damage detection in bridges
Adam Santos,Eloi Figueiredo,Moisés Silva,Reginaldo Santos,Claudomiro Sales,João C. W. A. Costa +5 more
TL;DR: In this paper, a hybrid approach based on a standard genetic algorithm (GA) was proposed to improve the stability of the EM algorithm on the searching of the optimal number of clusters and their parameters, strengthening the damage classification performance.
Journal ArticleDOI
Deep principal component analysis: An enhanced approach for structural damage identification:
Moisés Silva,Adam Santos,Adam Santos,Reginaldo Santos,Eloi Figueiredo,Claudomiro Sales,João C. W. A. Costa +6 more
TL;DR: The experimental results demonstrate that capturing the most slight nonlinear variations in the data can lead to improved data normalization and, consequently, better damage detection and quantification performances.
