摘要
En 中文
Nearest neighbor classifiers demand significant computational resources (time and memory). Editing of the reference set and feature selection are two different approaches to this problem. Here we encode the two approaches within the same genetic algorithm (GA) and simultaneously select features and reference cases. Two data sets were used: the SATIMAGE data and a generated data set. The GA was found to be an expedient solution compared to editing followed by feature selection, feature selection followed by editing, and the individual results from feature selection and editing.
