%X Reduction of attribute is one of the important topics in the search of rough set theory. Although many algorithms for reduction of attribute have been proposed,most of them have some defects. On the other hand,parallel genetic algorithm has some advantages to deal with huge data sets. In this paper,rough entropy is used to measure the uncertainties of rough set. Then a new three population parallel genetic algorithm is presented to solve reduction of attribute from data sets. It is testified by the experime...
