Generalized Multi-Context Systems

چکیده
Multi-context systems (MCSs) define a versatile framework for integrating and reasoning about knowledge from different (heterogeneous) sources. In MCSs, different types of nonmonotonic reasoning are characterized by different semantics such as equilibrium semantics and grounded equilibrium semantics [Brewka and Eiter, 2007]. We introduce a novel semantics of MCSs, a supported equilibrium semantics. Our semantics is based on a new notion of support. The “strength” of supports determines a spectrum of semantics that, in particular, contains the equilibrium and grounded equilibrium semantics. In this way, our supported equilibrium semantics generalizes these previously defined semantics. Moreover, the “strength” of supports gives us a measure to compare different semantics of MCSs.

Using Context-based Statistical Models to Promote the Quality of Voice Conversion Systems
This article aims to examine methods of optimizing GMM-based voice conversion systems performance in which GMM method is introduced as the basic method for improvement of voice conversion systems performance. In the current methods, due to using a single conversion function to convert all speech units and subsequent spectral smoothing arising from statistical averaging, we will observe quality ...
متن کاملUtilizing Generalized Learning Automata for Finding Optimal Policies in MMDPs
Multi agent Markov decision processes (MMDPs), as the generalization of Markov decision processes to the multi agent case, have long been used for modeling multi agent system and are used as a suitable framework for Multi agent Reinforcement Learning. In this paper, a generalized learning automata based algorithm for finding optimal policies in MMDP is proposed. In the proposed algorithm, MMDP ...
متن کاملDetection and Recognition of Multi-language Traffic Sign Context by Intelligent Driver Assistance Systems
Design of a new intelligent driver assistance system based on traffic sign detection with Persian context is concerned in this paper. The primary aim of this system is to increase the precision of drivers in choosing their path with regard to traffic signs. To achieve this goal, a new framework that implements fuzzy logic was used to detect traffic signs in videos captured along a highway f...
متن کاملDevelopment of a Set of Algorithms for the Multi-Project Scheduling Problems
In this paper, the problem of determining the best schedule for a set of projects has been modeled in the form of a generalized tardiness flowshop (GTF) problem. We develop a set of heuristic algorithms for minimizing the total tardiness of jobs in a GTF problem. In the generalized version of tardiness flowshop problems, a job is considered to be a collection of operations and there is a due da...
متن کاملAn improved similarity measure of generalized trapezoidal fuzzy numbers and its application in multi-attribute group decision making
Generalized trapezoidal fuzzy numbers (GTFNs) have been widely applied in uncertain decision-making problems. The similarity between GTFNs plays an important part in solving such problems, while there are some limitations in existing similarity measure methods. Thus, based on the cosine similarity, a novel similarity measure of GTFNs is developed which is combined with the concepts of geometric...

In the present paper, a class of hybrid, nonlinear and non linearizable dynamic systems is considered. The noted dynamic system is generalized to a multi-agent configuration. The interaction of agents is presented based on graph theory and finally, an interaction tensor defines the multi-agent system in leader-follower consensus in order to design a desirable controller for the noted system.
