TL;DR: A new informative measure for discrimination between two fuzzy sets is introduced and it is shown that this discriminating measure reduces to the nonprobabilistic entropy of Deluca and Termini under a special condition.

TL;DR: Interpolative reasoning in the strict sense can be applied and can be extended to a form of extrapolation, when the observation is not flanked from both sides, and then the idea is extended to arbitrary approximation.

TL;DR: Some properties of fuzzy quasi-ideals of a Semigroup are given and a completely regular semigroup and a semigroup that is a semilattice of groups in terms of fuzzy semiprime quasi-Ideals are characterized.

TL;DR: F fuzzy mathematical programming problems are formulated based on the idea analogous with the chance constrained programming problem, where the difference in meaning between the ambiguity of the coefficients and that of the decision maker's preference is emphasized.

TL;DR: It is shown that any feasible solution of the TSP instance G can be transformed into a feasible solutionOf the GT SP instance G of no greater cost, and that any optimal solution ofThe TSP instances G can been transformed into an optimal solutionof the GTSP instanceG.

TL;DR: A class of new learning algorithms for massively parallel networks of simple computing elements that attempt to overcome some of the limitations of some approaches to learning in networks that rely on modification of weights on the links within an otherwise fixed network topology are developed.

TL;DR: A distributed algorithm is presented for constructing a nearly optimal Steiner tree in an asynchronous network represented by a weighted communication graph G = (V, E, c) where G is the subset of nodes of G to be connected.

TL;DR: A new simple self-stabilizing distributed algorithm for coloring a bipartite graph has been proved to be correct, and the simple reasoning-based proof technique seems to have potential to be useful in proving correctness of other self-Stabilizing algorithms for graph theoretical problems.

TL;DR: The lattice of fuzzy equivalence (congruence) relations on a semigroup gives certain lattice theoretic properties and the fuzzy congruence relation generated by a given fuzzy relation on aSemigroup is studied.

TL;DR: A network of probabilistic cellular automata (PCAs) for iteratively resolving ambiguities and conflicts in pattern recognition and a different architecture for describing the model from that used in Bayesian inference networks.

TL;DR: The multisensor integration system based on the neural network and fuzzy inference techniques is used to use both accurate sensors and long measurement range sensors for precise carving and fast approach.

TL;DR: This paper adopts an alternative point of view for determining the values of the fuzzy measure from few data by interactively changing equation constraints and will contribute to increasing the applicability and the fuzzy integral in the field of decision support systems.

TL;DR: This paper investigates the use of a penalty function to help guide in the aggregation process and shows that logical inference systems are characterized by infinite penalty functions and that deviation from the data are not easily accepted.

TL;DR: A new approach to the problem of extending interval order relations to the case of fuzzy interval numbers is presented, using the connectedness between fuzzy sets and random sets as a guide.

TL;DR: Classes of bag operators that generalize the multivalued logic “and” and “or” operators are introduced and the concept of value functionality is introduced to include associativity.

TL;DR: If the start condition is of random context type, the effect of different conditions for starting and stopping of the components of the grammar system is studied, and at most all matrix languages and the family of context-sensitive languages are obtained.

TL;DR: Subgroups and normal subgroups of a fuzzy group are defined and their criteria are established, and the fuzzy order of an element of a group is defined, and its relationship with the order of the element is examined.

TL;DR: This work gives sufficient conditions for A to have a basis over a fuzzy subfield K of F and shows that if A has the sup property, then A has a fullyfree basis over F but not necessarily a fully free basis over K.

TL;DR: A total measure of uncertainty in the Dempster-Shafer theory, defined as the sum of discord and nonspecificity, is discussed in the paper, which is oriented toward a mathematical consideration of the measure of discord.

TL;DR: The two-degree-of-freedom fuzzy model uses associative memories to achieve operation and prediction close to those of human beings to represent the featured phenomenon.

TL;DR: The computation complexity of temporal constraint satisfaction on causal models is analyzed, showing that such a form of reasoning is intrinsically intractable, but it is shown that it is possible to define sufficient conditions for temporal consistency that can be checked in polynomial time.

TL;DR: A construction method of the behavior-decision system using fuzzy algorithms capable of expressing sequence flow which includes a mixture of both crisp and fuzzy processing and a method of tuning algorithms for giving robots the autonomous ability to judge purposes of actions like human is proposed.

TL;DR: An experience-based decoupling method for designing fuzzy logic controllers is proposed, able to reduce the number of rules and by introducing some mediate (state) variables, is able to use the same set of fuzzy rules for three-stage inverted pendulum and one-stage inverted pendulum.

TL;DR: This paper shows that the problems of sorting and computing convex hulls can be solved in O(1) time on two-dimensional processor arrays with reconfigurable bus systems.

TL;DR: Two basic types of computational nodes performing generalized (weighted) AND and OR operations form generic components of neural networks and the combination of these two nodes into a structure of logic processors is used to approximate manyinput-single-output logical relationships.

TL;DR: Convergence properties for reciprocal fuzzy matrices are established andemplary applications are discussed, including examples of practical applications of the property.

TL;DR: A sum of real numbers equals the mutual entropy of a fuzzy set and its complement set and the proof uses the logistic map, a diffeomorphism that maps extended real space onto the fuzzy cube embedded in it.

TL;DR: An active semantic database model that copes with the issues of automatic enforcement of dependencies among various portions of fragmented (possibly heterogenous) database and relevant implementation issues is described.
