Abstract:

In this paper,the discretization problem in Rough Set is discussed. We do classification research on the discretization algorithm from different viewpoints, Several discretization algorithms are introduced and discussed. We improve the greedy algorithm in different ways. We present a strategy for discretization based on the importance of condition attributes. In the end, we present the goal of discretization based on experiments.
