2. Since Aristotle we are used to Classical Logic with only 2 possible outcomes. To observe these extreme views, compare the classical- and fuzzy-control analysis of a … This view shapes this work, reflecting the authors' subjective balance between the scientific and pedagogic components of the textbook. In traditional logic an object takes on a value of either zero or one. For example, using our example of speed on the highway, 90 km/h in classical logic is a slow speed; while 90 km/h in fuzzy logic is not totally fast but it is not totally slow either. Generally most of the tuning methods depend mainly on the experimental approach of open-loop unit step response. 2015-08-16 5 Beyond your imagination swinsolutions.com Fuzzy Set Theory vs. Therefore truthness of a proposition P is membership value of x in fuzzy set A. It shows that fuzzy set theory is a mathematically rigorous and comprehensive set theory useful in characterizing concepts with natural ambiguity. This book aims to justify the use of fuzzy logic as a logic and as an uncertainty theory in the decision-making context. Set: A set is defined as a collection of objects, which share certain characteristics. In fuzzy logic, a value can belong to several sets at once, unlike classical logic. So the most important difference between fuzzy logic and probabilistic logic seems to be that in probabilistic logic you do not deal with degrees of truth, only degrees of belief. Instead of just black and white, it employs the spectrum of colours, accepting that things can be partly true and partly false at the same time. A coin that is thrown has a chance of 0.5 for landing heads up. The primary purpose of this course is to introduce students to the important areas of fuzzy set theory and fuzzy logic. FUZZY LOGIC Fuzzy logic is the logic underlying approximate, rather than exact, modes of reasoning. 1. generated voltage in a vector control system. 18. Control Engineering | Temperature control: PID vs. classical mechanics; fuzzy … Fuzzy logic and probability theory are two independent sources of indeterminacy in judging if an element x ∈ A is in a set. The book is written for professionals, researchers and students working in philosophy of science, decision-choice theories, economies, sciences, computer science, engineering, cognitive psychology and researchers working on, or interested ... It is important to know the difference between fuzzy logic and chance. Found inside – Page 3426Classical fuzzy sets by their use of membership functions which extend over the domain ( 0 , 1 ) accord a unique value to the ... The author proposes a suitable axiomatization of an extension of the propositional basic logic ( BL ) that introduces unary ... In doing this they distinguish the continuous case ( where one ... Precisely, we present an example to show that, in the fuzzy context, the fact that the supremum is naturally used in lieu of the union can alter an argument that may work in the classical context. We have discussed only binary valued logic and classical set theory like : A person belongs to a set of all human beings, and if given a specific subset, say all males, then one can say whether or not the particular person belongs to this set. Crisp Sets and logic. Fuzzy Logic Controllers, when well designed, can behave like a nonlinear controller or even like a set of linear PID controllers that operate differently according to the stimuli or inputs. 2. From its inception fuzzy logic has had a close relationship with probability. Nearly almost all logics of probability that have been proposed in the literature are based on classical two-valued logic. The classical approach based on the PI control is first considered and thena fuzzy -logic-based alternative is proposed. This book comprises a selection of papers on theoretical advances and applications of fuzzy logic and soft computing from the IFSA 2007 World Congress, held in Cancun, Mexico, June 2007. A fuzzy controller can include empirical rules, and that is especially useful in operator controlled plants. Found inside – Page 115is reduced to the problem of translating the meanings of the relevant ... So, the main difference between classical and fuzzy rules is that in the latter ... In particular, two different-type fuzzy logic (FL) controllers, Mamdani and Sugeno, are developedfor the purpose. In classical logic, a simple proposition P is a linguistic, or declarative, statement contained within a universe of elements, X, that can be identified as being a collection of elements in X that are strictly true or strictly false. The analysis and comparison of the Suppose a fuzzy proposition ‘P’ is assigned to a fuzzy set ‘A’, then the truth value of the proposition is proposed by T (P) = μ A (x) where 0 ≤ μ A (x) ≤ 1. This book provides an accessible and up-to-date introduction to this fast-growing and increasingly popular area. The designed Fuzzy logic controller technique can find peak power by doing wide range of illumination and temperature variations (Ghassami et al. A fuzzy set assigns a degree of membership, typically a real number from the interval [0,1], to elements of a universe. To put it in more precise mathematical terms, classical logic has two values. Expressed in the black and white language of Boolean logic. These are exciting times in the fields of Fuzzy Logic and the Semantic Web, and this book will add to the excitement, as it is the first volume to focus on the growing connections between these two fields. Fuzzy logic is intended to model logical reasoning with vague or imprecise statements like “Petr is young (rich, tall, hungry, etc.)”. Previously the theory of crisp sets based in dual logic is used in the computing and formal reasoning which involves the solutions in either of two form such as “yes or no” and “true or false”. Unlike crisp logic, in fuzzy logic, approximate human reasoning capabilities are added in order to apply it to the knowledge-based systems. Fuzzy vs Classical Logic in AI. 4 Foundations of Fuzzy Logic . Explore the diverse electrical engineering application of polymer composite materials with this in-depth collection edited by leaders in the field Polymer Composites for Electrical Engineering delivers a comprehensive exploration of the ... Fuzzy propositions are assigned to fuzzy sets. In mathematics and computer science, the gradations of applicable meaning of a fuzzy concept are described in terms of quantitative relationships defined by logical operators. Vector control algorithms are often used for control of the self-excited induction generators (SEIGs). A fuzzy logic-based two-axis solar tracking system increases efficiency by 33.416 % compared to a non-tracking system. Introduction to Neural Networks using MATLAB 6.0 - S.N.Sivanandam, S.Sumathi, S.N.Deepa, TMH, 2006 ADDITIONAL TOPICS 1. Comparison of some Classical PID and Fuzzy Logic Controllers Eisa Bashier M. Tayeb and A. Taifour Ali Abstract— The proportional-integral-derivative (PID) controller is tuned to find its parameters values. If x is precisely known and A is clearly defined, then x ∈ A is either true or false, following the "law of excluded middle". Fuzzy logic is primarily based on this theory, which is a generalisation of the classical theory of set (i.e., crisp set) introduced by Zadeh in 1965. Fuzzy logic Fuzzy logic differs from classical logic in that statements are no longer black or white, true or false, on or off. We discuss a fuzzy result by displaying an example that shows how a classical argument fails to work when one passes from classical logic to fuzzy logic. Classical set theory assumes that any element (company) fully belongs or completely does This is followed by discussions and establishment of the epistemic foundations of fuzzy mathematics where the nature and role of information and knowledge are explicated and represented. It can be implemented in hardware, software, or a combination of both. Found insideEven if the membership functions are restricted to be Type1, their combinations generate an interval – valued Type 2 membership. This is part of the general result that Classical equivalences breakdown in Fuzzy theory. 2.1 Fuzzy sets vs. crisp sets. Fuzzy advantages: some predicates may entirely apply or entirely fail to apply. Fuzzy logic applications: Fuzzy logic control and Fuzzy classification. This book presents fuzzy logic as the mathematical theory of vagueness as well as the theory of commonsense human reasoning, based on the use of natural language, the distinguishing feature of which is the vagueness of its semantics. Classical Sets Fuzzy Relation Equations Basic Concepts On Fuzzy Sets Possibility Theory Fuzzy Sets Versus Crisp Sets Fuzzy Logic Operations On Fuzzy Sets Uncertainty-Based Information Interval Arithmetic Approximate Reasoning Fuzzy Numbers ... This is how classical logic works. • Fuzzy Set theory is an extension of Classical set theory where elements have degree of membership. This is followed by individual chapters on topics relevant to earth scientists: sediment modeling, fracture detection, reservoir characterization, clustering in geophysical data analysis, ground water movement, and time series analysis. also in: THE KLUWER INTERNATIONAL SERIES ON ASIAN STUDIES IN COMPUTER AND INFORMATION SCIENCE, Volume 2 Classical relations and fuzzy relations 1. Dr. Qadri Hamarsheh 5 0 1 0.375 A 0.75 B o In classical set, Union represents all the elements in the universe that reside in either the set A, the set B or both sets A and B.This operation is called the logical OR. Boolean and fuzzy logic (a) Boolean Logic. This book provides readers with a snapshot of the state-of-the art in fuzzy logic. integral control (Fuzzy PI), a fuzzy logic control (FLC) and a classical proportional integral (PI) control. Main difference between fuzzy logic and prob- ability theory In our opinion any serious discussion on the relation between fuzzy logic and probability must start by mak- ing clear the basic differences. Introduction This is an introductive study on what Fuzzy Logic is, on the difference between Fuzzy Logic and the other many-valued calculi and on the possible relationship between Fuzzy Logic and the complex sciences. HistoryFuzzy logic is an infinite valued logic originally based upon the work of Polish logician Jan Lukasiewicz circa 1920. Therefore, fuzzy logic is a process to describe the human inclination of accurate thinking that is the generalization of classical logic. What is the difference between classical logic and fuzzy logic? Classical is contrasted with relevant, constructive, fuzzy… Difference between classical logic and fuzzy logic in soft computing - 6006642 anjalipant4360 anjalipant4360 04.10.2018 Computer Science Secondary School answered Difference between classical logic and fuzzy logic in soft computing 1 See answer anjalipant4360 is waiting for your help. From its inception fuzzy logic has had a close relationship with probability. Fuzzy Set. This book presents a mathematically-based introduction into the fascinating topic of Fuzzy Sets and Fuzzy Logic and might be used as textbook at both undergraduate and graduate levels and also as reference guide for mathematician, ... Fuzzy logic is supposed to be used for reasoning about inherently vague concepts, such as 'tallness.' Fuzzy logic means not clear or noisy whereas crisp logic is precise the answer can be either yes/no or True/False. Real World Problems •Uncertainty •Ambiguity Imprecision and Vague Data FUZZY LOGIC SYSTEM Decision Fuzzy Logic System & Real world Problems. Crisp Set. Note that the preservation of union on is over a countable set. Fuzzy Logic in Financial Management 263 where Í A: X o [0,1] is a function for each element of X that determines the extent to which it belongs to set A. -A set with fuzzy boundaries, such as short, average, or tall for height.-fuzzy sets are sets of mathematical principals for knowledge representation based on degrees of membership, while crisp sets are based on membership of classical binary logic. This book is an excellent starting point for any curriculum in fuzzy systems fields such as computer science, mathematics, business/economics and engineering. Fuzzy-PI, and that with a Fuzzy-PID controller with quite [9] D.E. Theorem 4 (see [9, Theorem ]). With fuzzy logic, a (calculated) value of 0.8 or 0.971 is possible. This article focuses on the basic ideas of fuzzy sets and systems. Fuzzy logic provide solution to such problems as it supports to multivalued propositions. Thus fuzzy logic is widely used for application development in many areas. In this book we tried to unveil the fuzzy logic concept. 3 Fuzzy logic controller (FLC) Classical controllers (P, PI, PID) are feedback controllers with fixed parameters. This book would be appropriate as a textbook for a general course in undergraduate liberal arts and sciences programs as a meaningful enrichment of a typical course on the basics of classical set theory and classical logic, and as a ... Key Features of Fuzzy Logic . It refers not to a fuzziness of logic but instead to a logic of fuzziness, or more specifically to the logic of fuzzy sets.Those that examined Lotfi A. Zadeh's concept more closely found it to be useful for dealing with real world phenomena. Question originally answered : What is the difference between probabilistic logic and fuzzy logic? Components of fuzzy logic. A ∪ B = {x/x ∈ A or x ∈ B}. It is an extension of multivalued logic: Everything, including truth, is a matter of degree. Their role is significant when applied to complex phenomena not easily described by traditional mathematics.The unique feature of the book is twofold: 1) It is the first introductory course (with examples and exercises) which brings in a ... Equivalence Relation Product Composition Classical Relation Fuzzy Relation Cartesian Space. Both systems depart from classical logic, but in different ways. It also illustrates two composition methods to relate elements of three or more universes. Also, recall the following result in . Thomas, B. Armstrong-Hélouvry: Fuzzy Logic Control- similar rules except in the acceleration term, and where A Taxonomy of Demonstrated Benefits, Proc. The main difference between classical set theory and fuzzy set theory is that the latter admits to partial set membership. Such an approach is sometimes called "degree-theoretic semantics" by logicians and philosophers, but the more usual term is fuzzy logic or many-valued logic. It also illustrates two composition methods to relate elements of three or more universes. In traditional logic an object takes on a value of either zero or one. This is truly an interdisciplinary book for knowledge workers in business, finance, management and socio-economic sciences based on fuzzy logic. Found inside – Page 480The previous comparison between classical and fuzzy control provokes a more general discussion of these two paradigms. Figure 13.41 shows a schematic ... Similar to the differences between set theory and fuzzy set theory, the difference between the phenomenon religion and the category religion merely affects the semantic level, but not the logical one. Haack has viewed fuzzy logic as an extension of classical logic and says that we do not need fuzzy logic [4]. of IEEE, the … Crisp set defines the value is either 0 or 1. This paper presents a comparative analysis of two different approaches for control of the SEIG’s generated voltage in a vector control system. A fuzzy control system is a control system based on fuzzy logic—a mathematical system that analyzes analog input values in terms of logical variables that take on continuous values between 0 and 1, in contrast to classical or digital logic, which operates on discrete values of either 1 or 0 (true or false, respectively Found insideThis volume is indispensable for all those who are interested in a deeper understanding of the mathematical foundations of fuzzy set theory, particularly in intuitionistic logic, Lukasiewicz logic, monoidal logic, fuzzy logic and topos-like ... Fuzzy Logic versus Classical Logic: An Example. It is acknowledged as a sort of multi-values logic obtained from the fuzzy set theory. In fuzzy logic, a value can belong to several sets at once, unlike classical logic. 0 0 0 1 1 1 0 0 0.2 0.4 0.6 0.8 1 1 Fuzzy logic uses the continuum of logical values between 0 (completely false) and 1 (completely true). This makes the book virtually self-contained. Throughout the book, many examples are used to illustrate concepts, methods, and generic applications as they are introduced. With fuzzy logic, a (calculated) value of 0.8 or 0.971 is possible. In this paper we deal with a new approach to probabilistic reasoning in a logical framework. Fuzzy logic emerged in the context of the theory of fuzzy sets, introduced by Zadeh (1965). 1. 2013). generated voltage in a vector control system. In a crisp set, an element is either a member of the set or not. For example, we might say that 'President Clinton is tall,' with degree of truth of 0.9. Title: CLASSICAL LOGIC and FUZZY LOGIC 1 CLASSICAL LOGIC and FUZZY LOGIC 2 CLASSICAL LOGIC. Difference between crisp logic and fuzzy logic. Therefore, they do not be able to adapt with environmental changes and to compensate parameter variations in plant. In classical logic, any statement is either true or false. Found inside – Page 106classical. to. fuzzy. logic: Principal ... Truth values, truth degrees The primary difference between many-valued logics and classical logic is that the set ... o For example, the union of tall men and fat men contains all men who are tall OR fat. The main part of the book is a comprehensive overview of the development of fuzzy logic and its applications in various areas of human affair since its genesis in the mid 1960s. classical mechanics; fuzzy … Found insideFuzzy Logic has gained increasing acceptance as a way to deal with complexity and uncertainty in many areas of science and engineering. This book is the first to address its practical applications to chemical systems. The classical view of concepts in psychology was challenged in the 1970s when experimental evidence showed that concept categories are graded and thus cannot be represented adequately by classical sets. For areas where every predicate applies fully or fails to apply at all to everything relevant, classical logic is just a special case of fuzzy logic, … For example, we might say that 'President Clinton is tall,' with degree of truth of 0.9. In logic, a many-valued logic (also multi-or multiple-valued logic) is a propositional calculus in which there are more than two truth values.Traditionally, in Aristotle's logical calculus, there were only two possible values (i.e., "true" and "false") for any proposition.Classical two-valued logic may be extended to n-valued logic for n greater than 2. Cite chapter. Controlled Vocabulary Terms. Fuzzy Logic Toolbox™ software uses the classical operator for the fuzzy complement as shown in the previous figure, but also enables you to customize the AND and OR operators. Fuzzy logic is supposed to be used for reasoning about inherently vague concepts, such as 'tallness.' This book provides an essential introduction to the field of dynamical models. In this post, we will discuss classical sets and fuzzy sets, their properties and operations that can be applied on them. This means that bivariate logic are special cases of fuzzy logic. It specifies the degree to which something is true. Fuzzy logic uses the continuum of logical values between 0 (completely false) and 1 (completely true). A ∪ B = {x/x ∈ A or x ∈ B}. Add your answer and earn points. At the same time Plato laid foundations for Fuzzy Logic, but it received decent attention only in the second half of the 20th century in Japan. Fuzzy Sets •DOM is usually [0 –1] but… –Could use 0 –255 (for int arithmetic speed) –Numbers are NOT probabilities nor percentages •Fuzzy logic: truth degrees to model vagueness •Probability theory: model non-determinism •Mutual exclusion –Classical: some predicates are M.E. 1. Fuzzy logic is closely related to sets, just like traditional bivariate logic. If there was a change, it was that the dependency on classical logic and, with that, on the modern paradigm, was increased. Perhaps the most striking difference between the two logics is the very nature of propositions themselves. To put it in more precise mathematical terms, classical logic has two values. Found inside – Page 71The differences between fuzzy-random and random-fuzzy in case of ... At the level of knowledge applications, fuzzy logic defines an important toolbox for ... This book presents the first algebraic treatment of quasi-truth fuzzy logic and covers the algebraic foundations of many-valued logic. It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false. CLASSICAL LOGIC. Fuzzy systems have been able to provide solutions to many real world problems. Classical Set Theory Swin Solutions Business Intelligence and Risk Management 7 0.22 0 … The intersection of two fuzzy sets A and B is specified in general by a binary mapping T , which aggregates two membership functions as follows: Fuzzy Logic and Probability. Fuzzy logic arises by assigning degrees of truth to propositions. Primitive operations of classical sets; Laws associated with classical sets; Primitive operations of fuzzy sets; Laws associated with fuzzy sets; Crisp Logic vs Fuzzy logic . However, in reality, due to insufficient knowledge or imprecise data, it is not always clear whether an object belongs to a set or not. This fu nction is called a membership function of fuzzy set A. CLASSICAL LOGIC AND FUZZY LOGIC Dr S.Natarajan Professor Department of Information Science and Engineering PESIT, Bangalore Classical Predicate Logic tautologies, Contradictions, Equivalence, Exclusive Or Exclusive Nor, Logical Proofs, Deductive Inferences Fuzzy Logic, Approximate Reasoning, Fuzzy Tautologies, Contradictions, Equivalence and Logical Proofs, Other … Classical logic cannot model thus, but fuzzy can. I couldn't tell you very much about quantum logic other than that it appears to have originated in … The analysis and comparison of the The standard Both forms of logic were invented to handle statements that create problems for classical logic. Register today and get certified in Fuzzy Logic Programming ... Fuzzy-Classical vs Fuzzy Sets. The classical approach based on the PI control is first considered and then a fuzzy-logic-based alternative is proposed. With an extensive bibliography, this book provides in-depth insight into fuzzy Semantic Web languages for non-fuzzy set theory and fuzzy logic experts. the truth value of variables may be any real number between 0 and 1. Found insideManaging vagueness/fuzziness is starting to play an important role in Semantic Web research, with a large number of research efforts underway. This volume includes, besides the original text of Deviant Logic, five papers on related topics, including two in fuzzy logic, and a supplementary bibliography of selected material published since the appearance of the first edition of the ... 3.4 The difference between a classical set and a fuzzy set. Instead of just black and white, it employs the spectrum of colours, accepting that things can be partly true and partly false at the same time. A classical or crisp set, then, is a fuzzy set that restricts its membership values to {0, 1}, the endpoints of the unit interval. Conclusion The fuzzy set theory is intended to introduce the imprecision and vagueness in order to attempt to model the human brain in artificial intelligence and significance of such theory is increasing day by day in the field of expert systems. ©Debasis Samanta, Indian Institute of Technology Kharagpur 1 Chapter 4 Fuzzy Proposition Main difference between classical proposition and fuzzy proposition is in the range of their truth values.

Found inside – Page 11Fuzzy Logic is not the key of the formalization of Natural Language Fuzzy ... not think that there is a great difference between classical and Fuzzy Logic. It contains as special cases not only the classical two-value logic and multivalue logic systems, but also probabilistic logic. Introduction. This book consists of selected papers written by the founder of fuzzy set theory, Lotfi A Zadeh. The classical set is defined in such a way that the universe of discourse is spitted into two groups members and non-members. Hence, In case classical sets, no partial membership exists. Let A is a given set. The membership function can be use to define a set A is given by: Operations on classical sets: For two sets A and B and Universe X: membership and the degree of truth. The veracity (truth) of an element in the proposition P can be assigned a binary A coin that is thrown has a chance of 0.5 for landing heads up. Relations
This chapter introduce the notion of relation.
The notion of relation is the basic idea behind numerous operations on sets suchas Cartesian products, composition of relations , difference of relations and intersections of relations and … Found insideIn the early 1970s, fuzzy systems and fuzzy control theories added a new dimension to control systems engineering. The main difference between classical set theory and fuzzy set theory is that the latter admits to partial set membership. Dr. Qadri Hamarsheh 5 0 1 0.375 A 0.75 B o In classical set, Union represents all the elements in the universe that reside in either the set A, the set B or both sets A and B.This operation is called the logical OR. Haack has viewed fuzzy logic as an extension of classical logic and says that we do not need fuzzy logic [4]. A classical or crisp set, then, is a fuzzy set that restricts its membership values to {0, 1}, the endpoints of the unit interval. Fuzzy Sets and Membership Functions . 2.1 Basics of Fuzzy Set Theory and Fuzzy Logic Fuzzy Sets In classical set theory, an individual object is either a member or a nonmember of a set. The approach of FL imitates the way of decision making in humans that involves all intermediate possibilities between digital values YES and NO. Fuzzy Logic, Knowledge and Natural Language Gaetano Licata Università degli Studi di Palermo Italy 1. The fuzzy set follows the infinite-valued logic whereas a crisp set is based on bi-valued logic. Fuzzy Logic, Knowledge and Natural Language Gaetano Licata Università degli Studi di Palermo Italy 1. 1) antecedent is true, consequent is true. Classical set. Fuzzy Logic is a logic or control system of an n-valued logic system which uses the degrees of state “degrees of truth“of the inputs and produces outputs which depend on the states of the inputs and rate of change of these states (rather than the usual “true or false” (1 or 0), Low or High Boolean logic (Binary) on which the modern computer is based).

2. Fuzzy Sets for an Industrial Examples . Found inside – Page iThe content within this publication represents the work of particle swarms, fuzzy computing, and rough sets. Recall from that a fuzzy semistar operation on is said to be union preserving if . It can assist us to organize words into clear and concise sentences. A great source of information on fuzzy sets and fuzzy logic can be found in a collection of frequently asked questions and corresponding answers. Fuzzy Logic . Let be a union preserving fuzzy semistar operation on . Found inside – Page 11Fuzzy Logic is not the key of the formalization of Natural Language Fuzzy ... not think that there is a great difference between classical and Fuzzy Logic. It contains as special cases not only the classical two-value logic and multivalue logic systems, but also probabilistic logic. Introduction. This book consists of selected papers written by the founder of fuzzy set theory, Lotfi A Zadeh. The classical set is defined in such a way that the universe of discourse is spitted into two groups members and non-members. Hence, In case classical sets, no partial membership exists. Let A is a given set. The membership function can be use to define a set A is given by: Operations on classical sets: For two sets A and B and Universe X: membership and the degree of truth. The veracity (truth) of an element in the proposition P can be assigned a binary A coin that is thrown has a chance of 0.5 for landing heads up. Relations
This chapter introduce the notion of relation.
The notion of relation is the basic idea behind numerous operations on sets suchas Cartesian products, composition of relations , difference of relations and intersections of relations and … Found insideIn the early 1970s, fuzzy systems and fuzzy control theories added a new dimension to control systems engineering. The main difference between classical set theory and fuzzy set theory is that the latter admits to partial set membership. Dr. Qadri Hamarsheh 5 0 1 0.375 A 0.75 B o In classical set, Union represents all the elements in the universe that reside in either the set A, the set B or both sets A and B.This operation is called the logical OR. Haack has viewed fuzzy logic as an extension of classical logic and says that we do not need fuzzy logic [4]. A classical or crisp set, then, is a fuzzy set that restricts its membership values to {0, 1}, the endpoints of the unit interval. Fuzzy Sets and Membership Functions . 2.1 Basics of Fuzzy Set Theory and Fuzzy Logic Fuzzy Sets In classical set theory, an individual object is either a member or a nonmember of a set. The approach of FL imitates the way of decision making in humans that involves all intermediate possibilities between digital values YES and NO. Fuzzy Logic, Knowledge and Natural Language Gaetano Licata Università degli Studi di Palermo Italy 1. The fuzzy set follows the infinite-valued logic whereas a crisp set is based on bi-valued logic. Fuzzy Logic, Knowledge and Natural Language Gaetano Licata Università degli Studi di Palermo Italy 1. 1) antecedent is true, consequent is true. Classical set. Fuzzy Logic is a logic or control system of an n-valued logic system which uses the degrees of state “degrees of truth“of the inputs and produces outputs which depend on the states of the inputs and rate of change of these states (rather than the usual “true or false” (1 or 0), Low or High Boolean logic (Binary) on which the modern computer is based).
