Abstract

This paper presents gene expression programming for attribution reduction in rough set (GEP-ARRS), which designs a new GEP code to convert attribution reduction into an expression tree and a new fitness function. Meanwhile, to solve optimal reduction, GEPARRS implements a dynamic population creation strategy to reduce the gene length of GEP to accelerate solution efficiency of GEP. Through extensive experiments on mass or high-dimensional data sets, it is shown that GEP-ARRS is apparently more advantageous in terms of speed and quality in contrast with traditional attribution reduction algorithms on intelligence computing.
