Dimensionality reduction of full fields by the principal components analysis

Abstract

http://www.iccm-central.org/Proceedings/ICCM17proceedings/Themes/Behaviour/FULL%20FIELD%20MEASU%20METH/F14.7%20Gogu.pdfInternational audienceThe principal components analysis is applied to simulated full field displacement maps of 4569 measurement points thus allowing representation of any field within a certain domain as a linear combination of five basis vectors without losing significant information. A dimensionality reduction from 4569 to only 5 is thus achieved
