ROUGH CLASSIFICATION IN INCOMPLETE INFORMATION SYSTEMS

open access: yesMathematical and Computer Modelling, 1989
The paper is concerned with the problems of rough sets theory and rough classification of objects. It is a new approach to problems from the field of decision-making, data analysis, knowledge representation, expert systems etc. Several applications (particularly in medical diagnosis and engineering control) confirm the usefulness of the rough sets idea.

Fuzzy Set-Valued Information Systems and the Algorithm of Filling Missing Values for Incomplete Information Systems

open access: yesComplexity, 2019
How to effectively deal with missing values in incomplete information systems (IISs) according to the research target is still a key issue for investigating IISs.

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 ...

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

Surface rearrangement at complex adsorbate-substrate interfaces [PDF]

open access: yes, 2004
On the basis of the information theory approach we propose a novel statistical scheme for analyzing the evolution of coupled adsorbate-substrate systems, in which the substrate undergoes the adsorbate-induced transformations.

Bounding trust in reputation systems with incomplete information [PDF]

open access: yesProceedings of the second ACM conference on Data and Application Security and Privacy, 2012
Reputation mechanisms represent a major class of techniques for managing trust in decentralized systems. Quite a few reputation-based trust functions have been proposed in the literature for use in many different application domains. However, in many situations, one cannot always obtain all of the information required by the trust evaluation process ...

Intelligent data attacks against power systems using incomplete network information: a review

open access: yesJournal of Modern Power Systems and Clean Energy, 2018
With the integration of information technologies, power system operations are increasingly threatened by cyber-attacks. It has even been revealed that an attacker can inject false data into real-time measurements stealthily without knowing the full ...

Controlling the Stochastic Sensitivity in Nonlinear Discrete-Time Systems with Incomplete Information

open access: yesDiscrete Dynamics in Nature and Society, 2015
For stochastic nonlinear discrete-time system with incomplete information, a problem of the stabilization of equilibrium is considered. Our approach uses a regulator which synthesizes the required stochastic sensitivity.
