Guerrero, N.M., Aparicio, J., Valero-Carreras, D. (2022) “Combining Data Envelopment Analysis and Machine Learning”, Mathematics, 10 (6):909

Nadia Guerrero, Juan Aparicio and Daniel Valero (Operations Research Center, University Miguel Hernández of Elche) 
Abstract: Data Envelopment Analysis (DEA) is one of the most used non-parametric techniques for technical efficiency assessment. DEA is exclusively concerned about the minimization of the empirical error, satisfying, at the same time, some shape constraints (convexity and free disposability). Unfortunately, […]

Alcaraz, J., Labbé, M., Landete, M. (2022) “Support Vector Machine with feature selection: A multiobjective approach”, Expert Systems with Applications, 204:117485

Javier Alcaraz, Mercedes Landete (Operations Research Center, University Miguel Hernández of Elche) and Martine Labbé (Computer Science Department, Université Libre de Bruxelles, Belgium)
Abstract: Support Vector Machines are models widely used in supervised classification. The classical model minimizes a compromise between the structural risk and the empirical risk. In this paper, we consider the Support Vector […]
