Abstract
The extended variable precision rough sets model incorporating asymmetric bounds is a generalisation of the original rough set theory. This paper introduces the (l, u)-quality graph, which elucidates the associated level of quality of classification (QoC), based on the choice of l and u values. A number of summary measures and lines are defined which pass over the domain of the (l, u)-quality graph. The defined lines are used to identify a choice of l and u values, based on retaining the underlying level of QoC from the whole (l, u)-quality graph.
