Embodiment Construction
[0033]The present invention will be further described below in conjunction with the accompanying drawings.
[0034] The implementation process of the present invention under the situation of fuzzy incremental dependence is as follows figure 1 As shown, the specific steps include:
[0035] Step1 The decision table is sorted by row according to the decision attribute value, then the first decision attribute set D is reordered to obtain the decision attribute set , then the set of conditional attributes Get conditional property collection after reordering ;
[0036] Step2 gather decision attributes Divide into 2≤p1 , Ω 2 、…Ω n}, and set conditional attributes according to the mapping relationship Divide the interval to get the interval set Γ={Γ 1 , Γ 2 、…Γ n}, where p is the number of intervals, and n is the number of objects in the decision table;
[0037] Step3 calculates the set of condition attributes in a loop from p to 2 The value of the membership functi...
