A multiobjective evolutionary setting for feature selection and a commonality-based crossover operator

Abstract: Abstract- Feature subset selection is a common and key\ud problem in many classification and regression tasks. It can\ud be viewed as a multi-objective optimisation problem, since,\ud in the simplest case, it involves feature subset size\ud minimisation and performance maximisation. Here, a\ud multiobjective evolutionary approach is proposed for\ud feature selection. A novel commonality-based crossover\ud operator is introduced and placed in the multiobjective\ud evolutionary setting. This specialised operator… Show more

“…We use a Subset Size-Oriented Common Feature Crossover Operator (SSOCF) [2] which keeps useful informative blocks and produces offspring's which have the same distribution than the parents. Offsprings are kept, only if they fit better than the least good individual of the population.…”

“…In this case, the authors were dealing with a handwritten word recognition task in which the original NSGA [11] was used as their search engine. It is also possible to introduce additional objectives related, for example, to cost [34] or some problem-specific characteristics [35]. This illustrates the flexibility that MOEAs provide when applied to pattern recognition tasks.…”
