Research of Granularity Pair and Dynamic Hierarchical Algorithm
Chunfeng Liu, Feng Li · 2010
The uncertainty of the border leads to the dynamics of granularity pair. In order to characterize the dynamic trend that the difference degree is close to the identity degree, the confidence threshold is introduced. Based on the positive correlation between the confidence threshold and the border of granularity pair, this paper proposes a new algorithm for dynamic hierarchy. The example shows that the algorithm is feasible.
