Multidimensional scaling of two-mode three-way asymmetric dissimilarities: finding archetypal profiles and clustering
Mireia Mollar-Gumbau, Aleix Alcacer, Rafael Benitez +2
Multidimensional scaling visualizes dissimilarities among objects and reduces data dimensionality. While many methods address symmetric proximity data, asymmetric and especially th…
Incorporating Fairness Constraints into Archetypal Analysis
Aleix Alcacer, Irene Epifanio
Archetypal Analysis (AA) is an unsupervised learning method that represents data as convex combinations of extreme patterns called archetypes. While AA provides interpretable and l…
A Survey on Archetypal Analysis
Aleix Alcacer, Irene Epifanio, Sebastian Mair +1
Archetypal analysis (AA) was originally proposed in 1994 by Adele Cutler and Leo Breiman as a computational procedure for extracting distinct aspects, so-called archetypes, from ob…
