Previous researchers have shown that this simultaneous evolution is a way to avoid the noisy fitness evaluation. The MA incorporates a crossover operator that shows to be useful for ameliorating the permutation problem of the network representation (i.e. different genotypes can be used to represent the same neural network phenotype), increasing the structural diversity of the individuals and improving the accuracy of the results. Instead of a recombination probability, the crossover operator considers a similarity parameter (the minimum structural distance), which allows to maintain a trade-off between global and local search. The neural network models selected in this work are the product-unit neural networks (PUNNs), due to their increasing relevance in those classification problems which show a high order relationship between the input variables. The proposed MA is intended to reduce the possible overtraining problems which can raise in some datasets for this kind of models. The evolutionary system is applied to eight classification benchmarks and the results of an analysis of variance contrast (ANOVA) show the effectiveness of the structural-based crossover operator and the capacity of our algorithm to obtain evolved PUNNs with a higher classification accuracy than those obtained using other evolutionary techniques. On the other hand, the results obtained are compared with popular effective machine learning classification methods, resulting in a competitive performance.<\/jats:p>","DOI":"10.1142\/s0218001412500127","type":"journal-article","created":{"date-parts":[[2012,10,5]],"date-time":"2012-10-05T06:05:34Z","timestamp":1349417134000},"page":"1250012","source":"Crossref","is-referenced-by-count":0,"title":["A STRUCTURAL DISTANCE-BASED CROSSOVER FOR NEURAL NETWORK CLASSIFIERS"],"prefix":"10.1142","volume":"26","author":[{"given":"MANUEL","family":"MORENO","sequence":"first","affiliation":[{"name":"Department of Computer Science and Numerical Analysis, University of C\u00f3rdoba, Campus de Rabanales, Edificio Albert Einstein, 2a planta, C\u00f3rdoba, 14071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"PEDRO ANTONIO","family":"GUTI\u00c9RREZ","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Numerical Analysis, University of C\u00f3rdoba, Campus de Rabanales, Edificio Albert Einstein, 2a planta, C\u00f3rdoba, 14071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C\u00c9SAR","family":"HERV\u00c1S-MART\u00cdNEZ","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Numerical Analysis, University of C\u00f3rdoba, Campus de Rabanales, Edificio Albert Einstein, 2a planta, C\u00f3rdoba, 14071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,12,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1016\/S0933-3657(02)00028-3"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1007\/0-387-33416-5"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1007\/s00500-008-0323-y"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1109\/72.265960"},{"key":"rf6","doi-asserted-by":"crossref","DOI":"10.1093\/oso\/9780195099713.001.0001","volume-title":"Evolutionary Algorithms in Theory and Practice","author":"Back T.","year":"1996"},{"key":"rf7","volume-title":"Neural Networks for Pattern Recognition","author":"Bishop C.
