TL;DR: This work presents a new interactive data visualization approach based on mixture of the outcomes of dimensionality reduction (DR) methods, whose weighting factors are defined by the user through a visual and intuitive interface.
Journal ArticleDOI
A data set for electric power consumption forecasting based on socio-demographic features: Data from an area of southern Colombia.
Jorge Parraga-Alava,Jorge Dario Moncayo-Nacaza,Javier Revelo-Fuelagán,Paul D. Rosero-Montalvo,Andres J. Anaya-Isaza,Diego Hernán Peluffo-Ordóñez +5 more
TL;DR: A data set concerning electric-power consumption-related features registered in seven main municipalities of Nariño, Colombia, from December 2010 to May 2016 is introduced, aimed at providing researchers a suitable input for designing and assessing the performance of forecasting, modelling, simulation and optimization approaches applied to electric power consumption prediction and characterization problems.
Book ChapterDOI
On the relationship between dimensionality reduction and spectral clustering from a kernel viewpoint
Diego Hernán Peluffo-Ordóñez,Miguel A. Becerra,Andrés Eduardo Castro-Ospina,X. P. Blanco-Valencia,Juan C. Alvarado-Pérez,Roberto Therón,Andres J. Anaya-Isaza,Andres J. Anaya-Isaza +7 more
TL;DR: This paper presents the development of a unified view of spectral clustering and unsupervised dimensionality reduction approaches within a generalized kernel framework in terms of a high-dimensional representation of the input data matrix incorporated into a least-squares support vector machine to yield a generalized optimization problem.
