Resumo: | From the set of dimensionality reduction techniques, we focus on the feature selection, a possible approach to carry it out is the use of Logical Analysis of Inconsistent Data (LAID). Recently, studies have demonstrated its potential in solving this problem and highlighted its advantages as a robust methodology, easy to interpret, and additionally capable of dealing with inconsistent data. The same studies revealed processing times higher than desired for full use and recommended the execution of algorithms through parallel processing using high-performance computing (HPC). This work represents yet another contribution to this effort by addressing ways of storing data, solutions for parallelizing algorithms, configuring the HPC environment, and finally testing the National Infrastructure for Distributed Computing (INCD) that allowed us to draw the conclusions presented. |

Recentemente vários estudos demostraram as suas potencialidades na resolução deste problema e evidenciaram as suas vantagens como uma metodologia robusta, de fácil interpretação e adicionalmente capaz de lidar com dados inconsistentes. Os mesmos estudos revelaram tempos de processamento acima do desejado para uma utilização plena e preconizaram a execução dos algoritmos através de processamento paralelo com recurso a computação de alto desempenho (HPC). Este trabalho representa mais um contributo nesse esforço ao abordar formas de armazenamento dos dados, soluções de paralelização dos algoritmos, configuração do ambiente HPC e finalmente os testes na Infraestrutura Nacional de Computação Distribuída (INCD) que permitiram extrair as conclusões apresentadas.Universidade Aberta2021-12-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.34627/rcc.v16i0.266https://doi.org/10.34627/rcc.v16i0.266Revista de Ciências da Computação; v. 16 (2021); 93-1122182-18011646-633010.34627/rcc.v16i0reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://journals.uab.pt/index.php/rcc/article/view/266https://journals.uab.pt/index.php/rcc/article/view/266/221Direitos de Autor (c) 2021 Universidade Abertahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMorgado, PauloCavique, Luís2022-12-23T06:30:14Zoai:ojs2.journals.uab.pt:article/266Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:14:02.490536Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
