A new dominance relation is defined in set-valued information system based on similarity grade of attribute value sets the problem of attribute reduction and the judgment in set-valued information system are studied, from which a new approach to attribute reductions is provided in set-valued information system, and the influence of similarity level on attribute reduction are discussed..

With hundreds or thousands of attributes in high-dimensional data, the computational workload is challenging. Attributes that have no meaningful influence on class predictions throughout classification process increase computing load. This article's goal to use attribute selection reduce size which will lessen Considering selected subsets cover all attributes. As a result, there are two stages ...

There are two methods for GIS similarity measurement problem, one is cross-coefficient for GIS attribute similarity measurement, and the other is spatial autocorrelation that is based on spatial location. These methods can not calculate subzone similarity problem based on universal background. The rough measurement based on membership function solved this problem well. In this paper, we used ro...

The paper investigates some similarity measures in interval bipolar neutrosophic environment for multi-attribute decision making problems. At first, we define Hamming and Euclidean distances measures between interval bipolar neutrosophic sets and establish their basic properties. We also propose two similarity measures based on the Hamming and Euclidean distance functions. Using maximum and min...
