    • openAccess   A data-driven classification of 3D foot types by archetypal shapes based on landmarks 

      Alcacer Sales, Aleix; Epifanio, Irene; Ibáñez Gual, Maria Victoria; Simó, Amelia; Ballester, Alfredo Costin Daniel Untaroiu (Virginia Tech, USA) (2020-01-30)
      The taxonomy of foot shapes or other parts of the body is important, especially for design purposes. We propose a methodology based on archetypoid analysis (ADA) that overcomes the weaknesses of previous methodologies used ...

    • openAccess   Archetype analysis: A new subspace outlier detection approach 

      Cabero-Fayos, Ismael; Epifanio, Irene; Piérola Orcero, Ana; Ballester, Alfredo Elsevier (2021)
      The problem of detecting outliers in multivariate data sets with continuous numerical features is addressed by a new method. This method combines projections into relevant subspaces by archetype analysis with a nearest ...

    • openAccess   Combining Classification and User-Based Collaborative Filtering for Matching Footwear Size 

      Alcacer Sales, Aleix; Epifanio, Irene; Valero, Jorge; Ballester, Alfredo MDPI (2021)
      Size mismatch is a serious problem in online footwear purchase because size mismatch implies an almost sure return. Not only foot measurements are important in selecting a size, but also user preference. This is the ...
