摘要:
在形式背景中引入上、下近似算子和上、下近似协调集引入证据理论的信任函数与似然函数,讨论它们与上、下近似协调集的关系,进而得到决策形式背景的下近似协调与粒协调是等价的.
Abstract:
In this paper, the upper and lower approximation operators and the upper and lower approximation consistent sets are introduced into formal context. The belief and plausibility functions from the evidence theory are employed to characterize upper and lower approximation consistent sets. Then the equivalence between lower approximation consistent and granular consistent of decision formal context is obtained.
