Abstract:

Feature and Instance Selection are two effective data reduction processes which can be applied to classification tasks obtaining promising results. Although both processes are defined separately, it is possible to apply them simultaneously.

This paper proposes an evolutionary model to perform Feature and Instance Selection in nearest neighbour classification. It is based on Cooperative Coevolution, which has been applied to many computacional problems with great success.

The proposed approach is compared with a wide range of evolutionary feature and instance selection methods for classification. The results contrasted through nonparametric statistical tests show that our model outperforms previously proposed evolutionary approaches for performing data reduction processes in combination with the nearest neighbour rule.
