Archetypal contour shapes
Università di Cassino e del Lazio Meridionale. Centro Editoriale di Ateneo (2019)Shapes are represented by contour functions from planar object outlines. Functional archetypal analysis is proposed to describe closed contour shapes. Each contour function is approximated by a convex combination of ... -
Detecting and visualizing differences in brain structures with SPHARM and functional data analysis
Elsevier (2020-08-07)A new procedure for classifying brain structures described by SPHARM is presented. We combine a dimension reduction technique (functional principal component analysis or functional independent component analysis) with ...

Finding archetypal patterns for binary questionnaires
Institut d'Estadística de Catalunya (Idescat) (2020-01)Archetypal analysis is an exploratory tool that explains a set of observations as mixtures of pure (extreme) patterns. If the patterns are actual observations of the sample, we refer to them as archetypoids. For the first ...

Robust archetypoids for anomaly detection in big functional data
Springer (2020-08-03)Archetypoid analysis (ADA) has proven to be a successful unsupervised statistical technique to identify extreme observations in the periphery of the data cloud, both in classical multivariate data and functional data. ...
