Spider-Man, the Child and the Trickster -- Archetypal Analysis in R [PDF]
, 2008 Archetypal analysis has the aim to represent observations in a multivariate data set as convex combinations of extremal points. This approach was introduced by Cutler and Breiman (1994); they defined the concrete problem, laid out the theoretical ...

Archetypal analysis for ordinal data
Information Sciences, 2021 Archetypoid analysis (ADA) is an exploratory approach that explains a set of continuous observations as mixtures of pure (extreme) patterns. Those patterns (archetypoids) are actual observations of the sample which makes the results of this technique easily interpretable, even for non-experts.

Archetypal analysis for machine learning [PDF]
2010 IEEE International Workshop on Machine Learning for Signal Processing, 2010 Archetypal analysis (AA) proposed by Cutler and Breiman in [1] estimates the principal convex hull of a data set. As such AA favors features that constitute representative 'corners' of the data, i.e. distinct aspects or archetypes. We will show that AA enjoys the interpretability of clustering - without being limited to hard assignment and the ...

Archetypal Analysis++: Rethinking the Initialization Strategy
, 2023 Archetypal analysis is a matrix factorization method with convexity constraints. Due to local minima, a good initialization is essential, but frequently used initialization methods yield either sub-optimal starting points or are prone to get stuck in poor local minima.
