Incremental Attribute Reduction Algorithm Based on Incomplete Hybrid Order Information System

open access: yes工程科学与技术
Because the data in the big data environment presents the characteristics of dynamic updating, incremental attribute reduction is attracting increasing research attention in the field of rough set theory.

Attribute reduction algorithm of rough sets based on spatial optimization [PDF]

open access: yes
Rough set is one of the important methods for rule acquisition and attribute reduction. The current goal of rough set attribute reduction focuses more on minimizing the number of reduced attributes, but ignores the spatial similarity between reduced and ...

Attribute-Based Oblivious Access Control

open access: yes, 2012
In an attribute-based system (ABS), users are identified by various attributes, instead of their identities. Since its seminal introduction, the attribute-based mechanism has attracted a lot of attention.

Modelling and optimizing multiple attribute decisions by using fuzzy sets [PDF]

open access: yes
The purpose of this paper is to present a coherent perspective of modeling and optimizing multiple attribute decisions by using fuzzy sets. In management practice we face most of the time the situation in which a problem have several possible solutions ...

Efficient attribute reduction based on discernibility matrix

open access: yes, 2007
To reduce the time complexity of attribute reduction algorithm based on discernibility matrix, a simplified decision table is first introduced, and an algorithm with time complexity O(| C ∥ U |) is designed for calculating the simplified decision table ...
