It starts with an introduction to machine learning concepts and a real-world application from the energy domain. Then, unsupervised nearest neighbors (UNN) is introduced as efficient iterative method for dimensionality reduction. Various UNN models are developed step by step, reaching from a simple iterative strategy for discrete latent spaces to a stochastic kernel-based algorithm for learning submanifolds with independent parameterizations. Extensions that allow the embedding of incomplete and noisy patterns are introduced. Various optimization approaches are compared, from evolutionary to swarm-based heuristics. Experimental comparisons to related methodologies taking into account artificial test data sets and also real-world data demonstrate the behavior of UNN in practical scenarios. The book contains numerous color figures to illustrate the introduced concepts and to highlight the experimental results.  .Intelligent Systems Reference Library,1868-4408 ;51Engineering mathematicsEngineeringData processingArtificial intelligenceOperations researchMathematical and Computational Engineering ApplicationsArtificial IntelligenceOperations Research and Decision TheoryEngineering mathematics.EngineeringData processing.Artificial intelligence.Operations research.Mathematical and Computational Engineering Applications.Artificial Intelligence.Operations Research and Decision Theory.006.31519.5/36Kramer Oliver761919MiAaPQMiAaPQMiAaPQBOOK9910438057103321Dimensionality Reduction with Unsupervised Nearest Neighbors2513616UNINA
