A multi-objective approach for communication reduction in federated learning under devices heterogeneity constraints
Morell, José Ángel; Abdelmoiz Dahi, Zakaria; Chicano-García, José-Francisco
; Luque-Polo, Gabriel Jesús; Alba-Torres, Enrique (Elsevier, 2024-02-24)
Federated learning is a paradigm that proposes protecting data privacy by sharing local models instead of raw data during each iteration of model training. However, these models can be large, with many parameters, provoking ... -
A parallel evolutionary algorithm for prioritized pairwise testing of software product lines

Algoritmos de Optimización sobre Unidades de Proceso Gráfico
(Servicio de Publicaciones y Divulgación Científica, 2015)En la actualidad, han emergido nuevas plataformas de cómputo paralelo tales como las Unidades de Procesamiento Gráfico (GPUs, por sus siglas en inglés). Las GPUs están especialmente diseñadas para proporcionar un entorno ... -
An efficient discrete PSO coupled with a fast local search heuristic for the DNA fragment assembly problem
Abdelkamel, Ben Ali; Luque-Polo, Gabriel Jesús; Alba-Torres, Enrique (Elsevier, 2020)
This paper focuses on Particle Swarm Optimization (PSO) applied to the DNA fragment as- sembly problem. Existing PSO algorithms for this permutation-based combinatorial prob- lem use the Smaller Position Value (SPV) rule ... -
An efficient routing protocol for green communications in vehicular ad-hoc networks.
Toutouh-el-Alamin, Jamal; Alba-Torres, Enrique (ACM, 2011-07-12)
Vehicular ad-hoc networks (VANETs) provide the communications required to deploy Intelligent Transportation Systems (ITS). In the current state of the art there is a lack of studies on Green Communications (energy-efficiency) ... -
An Evolutionary Algorithm to Generate Real Urban Traffic Flows
Stolfi, Daniel H.; Alba-Torres, Enrique (Springer International Publishing, 2015)
In this article we present a strategy based on an evolutionary algorithm to calculate the real vehicle ows in cities according to data from sensors placed in the streets. We have worked with a map imported from OpenStreetMap ... -
Análisis inteligente de los sensores de un automóvil
(2020-11-20)Los vehículos son a día de hoy sistemas cada vez más complejos que incorporan múltiples sistemas electrónicos que controlan la mayor parte del vehículo. Esos sistemas se comunican mediante una red de buses llamada CAN ... -
Análisis metaheurístico en la logística inversa de residuos
