An ensemble of ordered logistic regression and random forest for child garment size matching
Pierola, A.; Epifanio, Irene; Alemany Mut, Sandra Elsevier (2016-11)Size fitting is a significant problem for online garment shops. The return rates due to size misfit are very high. We propose an ensemble (with an original and novel definition of the weights) of ordered logistic regression ... -
Apparel sizing using trimmed PAM and OWA operators
Ibáñez Gual, Maria Victoria; Epifanio, Irene; Simó, Amelia; Vinué Visús, Guillermo; Alemany Mut, Sandra; Domingo Esteve, Juan de Mata; Ayala Gallego, Guillermo Elsevier (2012-09)This paper is concerned with apparel sizing system design. One of the most important issues in the apparel development process is to define a sizing system that provides a good fit to the majority of the population. A ... -
Archetypal analysis: contributions for estimating boundary cases in multivariate accommodation problem
Epifanio, Irene; Vinué Visús, Guillermo; Alemany Mut, Sandra Elsevier (2012-12)The use of archetypal analysis is proposed in order to determine a set of representative cases that entail a certain percentage of the population, in the accommodation problem. A well-known anthropometric database has been ... -
Archetypoids: A new approach to define representative archetypal data
Vinué Visús, Guillermo; Epifanio, Irene; Alemany Mut, Sandra Elsevier (2015)The new concept archetypoids is introduced. Archetypoid analysis represents each observation in a dataset as a mixture of actual observations in the dataset, which are pure type or archetypoids. Unlike archetype analysis, ... -
Child t-shirt size data set from 3D body scanner anthropometric measurements and a questionnaire
Pierola, A.; Epifanio, Irene; Alemany Mut, Sandra Elsevier (2017-04)A dataset of a fit assessment study in children is presented. Anthropometric measurements of 113 children were obtained using a 3D body scanner. Children tested a t-shirt of different sizes and a different model for boys ... -
Modeling of female human body shapes for apparel design based on cross mean sets
Domingo Esteve, Juan de Mata; Ibáñez Gual, Maria Victoria; Simó, Amelia; Dura, Esther; Ayala Gallego, Guillermo; Alemany Mut, Sandra Elsevier (2014)This paper is concerned with a method to build prototypes of human bodies that can be used for apparel design. One of the most important issues in the apparel development process is to define a sizing system to provide a ... -
The k -means algorithm for 3D shapes with an application to apparel design
Vinué Visús, Guillermo; Simó, Amelia; Alemany Mut, Sandra Springer (2014-10-17)Clustering of objects according to shapes is of key importance in many scientific fields. In this paper we focus on the case where the shape of an object is represented by a configuration matrix of landmarks. It is well ... -
Towards a mean body for apparel design
Domingo Esteve, Juan de Mata; Simó, Amelia; Ibáñez Gual, Maria Victoria; Dura, Esther; Ayala Gallego, Guillermo; Alemany Mut, Sandra Elsevier (2016-08)This paper focuses on shape average with applications to the apparel industry. Apparel industry uses a consensus sizing system; its major concern is to fit most of the population into it. Since anthropometric measures ...
