Constrained tolerance rough set in incomplete information systems

open access: yesCAAI Transactions on Intelligence Technology, 2021
The tolerance rough set is developed as one of the outstanding extensions of the Pawlak's rough set model under incomplete information, and the limited tolerance relation is developed to overcome the problem that objects leniently satisfy the tolerance ...

Robust coverless steganography using limited mapping images

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
Coverless image steganography (CIS) has attracted significant attention because it can fundamentally resist steganalysis tools. Available CIS schemes are mainly divided into synthesis-based and mapping-based schemes.

Family of Maximal Consistent Alliance Interval Sets in Incomplete Heterogeneous Conflict Information System [PDF]

open access: yesJisuanji kexue yu tansuo
As effective tools for dealing with uncertainty, three-way decision models have been widely applied in the study of conflict analysis. However, existing three-way conflict analysis models are mostly based on single-type conflict information systems ...

Output feedback stable stochastic predictive control with hard control constraints

open access: yes, 2017
We present a stochastic predictive controller for discrete time linear time invariant systems under incomplete state information. Our approach is based on a suitable choice of control policies, stability constraints, and employment of a Kalman filter to ...

Shinren : Non-monotonic trust management for distributed systems [PDF]

open access: yes, 2010
The open and dynamic nature of modern distributed systems and pervasive environments presents significant challenges to security management. One solution may be trust management which utilises the notion of trust in order to specify and interpret security

Multi‐granularity decision rough set attribute reduction algorithm under quantum particle swarm optimization

open access: yesIET Cyber-systems and Robotics, 2022
The existing attribute reductions are carried out using equivalence relations under a complete information system, and there is less research on attribute reductions of incomplete information systems with new theoretical models such as multi‐granularity ...

Reinforcement learning for Order Acceptance on a shared resource [PDF]

open access: yes, 2002
Order acceptance (OA) is one of the main functions in business control. Basically, OA involves for each order a reject/accept decision. Always accepting an order when capacity is available could disable the system to accept more convenient orders in the ...

A Heuristic Attribute-Reduction Algorithm Based on Conditional Entropy for Incomplete Information Systems

open access: yesAxioms
With the continuous expansion of databases, the extraction of information has been an urgent research topic in many fields. As an effective method to remove redundant attributes, attribute reduction demonstrates extraordinary ability in simplifying ...
