Finding Small OBDDs for Incompletely Specified Truth Tables Is Hard
We present an efficient reduction mapping undirected graphs G with n = 2k vertices for integers k to tables of partially specified Boolean functions g : {0, 1}4k+1 {0, 1, } so tha...

On the evaluation of the decision performance of an incomplete decision table
As two classical measures, approximation accuracy and consistency degree can be extended for evaluating the decision performance of an incomplete decision table. However, when the...

Comments on "Fuzzy Probabilistic Approximation Spaces and Their Information Measures"
Some errors in our original paper in defining relative reduct with information measures are pointed out in this paper. It is shown that in our original work, Theorems 10 and 19 hol...

Local and Global Approximations for Incomplete Data
Abstract. For completely specified decision tables lower and upper approximations are unique, the lower approximation is the largest definable set contained in the approximated set...
