TLDR
A fuzzy algorithm is introduced which, though fuzzy rather than precise in nature, may eventually prove to be of use in a wide variety of problems relating to information processing, control, pattern recognition, system identification, artificial intelligence and, more generally, decision processes involving incomplete or uncertain data.
Abstract
Unlike most papers in Information and Control, our note contains no theorems and no proofs. Essentially, its purpose is to introduce a basic concept which, though fuzzy rather than precise in nature, may eventually prove to be of use in a wide variety of problems relating to information processing, control, pattern recognition, system identification, artificial intelligence and, more generally, decision processes involving incomplete or uncertain data. The concept in question will be called a fuzzy algorithm because it may be viewed as a generalization, through the process of fuzzification, of the conventional (nonfuzzy) conception of an algorithm. More specifically, unlike a nonfuzzy deterministic or nondeterministic algorithm (Floyd, 1967), a fuzzy algorithm may contain fuzzy statements, that is, statements containing names of fuzzy sets (Zadeh, 1965), by which we mean classes in which there may be grades of membership intermediate between full membership and nonmembership. To illustrate, fuzzy algorithms may contain fuzzy instructions such as:

Adaptive Security Policy Using User Behavior Analysis and Human Elements of Information Security

TL;DR: Analysis of human behavior, therefore, is the basis for an adaptive security policy and levels of trust are released, which are based on the rules that were previously established for the parameters that are necessary to establish the evidences of behavioral trust, in its different degrees.

Comments on some theories of fuzzy computation

TL;DR: The basic idea of this paper is that the presence of real numbers in the interval [0,1] forces us to refer to endless approximation processes ( as in recursive analysis) and not to processes terminating after a finite number of steps and giving the exact output (as in recursive arithmetic).

TL;DR: The objective of the paper is to establish the similarities and differences between fuzzy systems and neural networks and to discuss possible models for fuzzy neural networks which can be applied to system modeling and control.

A Modern Syllogistic Method in Intuitionistic Fuzzy Logic with Realistic Tautology

TL;DR: The fuzzy MSM methodology is illustrated by three specific examples, which delineate differences with the crisp MSM, address the question of validity values of consequences, tackle the problem of inconsistency when it arises, and demonstrate the utility of the concept of Realistic Fuzzy Tautology.
