Abstract

Consistent approximate representation space is a unified model for formal contexts, consistent formal decision contexts and inconsistent formal decision contexts. In this paper, notions of attribute reduction are first developed in a consistent approximate representation space, and then necessary and sufficient conditions of attribute reducts are proposed in a consistent approximate representation space. Finally, two methods of attribute reduction including discernibility matrix and discernibility function are given to calculate all attribute reducts in a consistent approximate representation space.
