  Fuzzy Logic (Stanford Encyclopedia of Philosophy)
A fuzzy subset A of a (crisp) set X is characterized by assigning to each element x of X the degree of membership of x in A (e.g., X is a group of people, A the fuzzy set of old people in X).
Fuzzy logic in the narrow sense is symbolic logic with a comparative notion of truth developed fully in the spirit of classical logic (syntax, semantics, axiomatization, truth-preserving deduction, completeness, etc.; both propositional and predicate logic).
This fuzzy logic is a relatively young discipline, both serving as a foundation for the fuzzy logic in a broad sense and of independent logical interest, since it turns out that strictly logical investigation of this kind of logical calculi can go rather far.

  Fuzzy Logic
Fuzzy logic is a branch of machine intelligence that helps computers paint gray, commonsense pictures of an uncertain world.
Fuzzy logic manipulates such vague concepts as "warm" or "still dirty" and so helps engineers to build air conditioners, washing machines and other devices that judge how fast they should operate or shift from one setting to another even when the criteria for making those changes are hard to define.
Fuzzy sets of two objects are points of the square,such as the point A. The union and the intersection of a fuzzy set A and its complement A* lie at the corners of an interior square.

 'Fuzzy' logic   (Site not responding. Last check: )
Professor Matthew Yen's research is focused on the application of "fuzzy logic" in the control of equipment such as heaters, motors, pumps, valves and sprinklers used in the food processing industry and other automated agricultural operations.
Generally speaking, the procedures of fuzzy logic control are these: A set of input data from an array of sensors is fed into the control system.
Besides temperature controls, fuzzy logic has been implemented or proposed for many other processes in food technology, namely aseptic processing; diagnosis of principle causes of breakage during drying; determination of key ingredients for new products; evaluation of the "doneness" of beef steak; intelligent irrigation; automated feeding systems; and so on.

 Fuzzy logic - Wikipedia, the free encyclopedia
Fuzzy logic is derived from fuzzy set theory dealing with reasoning that is approximate rather than precisely deduced from classical predicate logic.
Fuzzy logic can be used to control household appliances such as washing machines (which sense load size and detergent concentration and adjust their wash cycles accordingly) and refrigerators.
Basic propositional fuzzy logic is an axiomatization of logic where the conjunction is defined by a continuous t-norm, and the implication defined as residuum of the t-norm.

 Fuzzy Logic and Musical Decisions
Fuzzy models, on the other hand, are a fairly straightforward translation of the linguistic statements of a group of rules.
Fuzzy logic is a well defined discipline, and we should not play fast and loose with its conventions just because it deals with vagueness.
Fuzzy logic allows a vague description of the rules that will lead to a desired outcome, but it is still highly accurate and repeatable, given consistent initial conditions.

 Fuzzy
Inference from a set of fuzzy rules involves fuzzification of the conditions of the rules, then propagating the confidence factors (membership values) of the conditions to the conclusions (outcomes) of the rules.
While the main principles of fuzzy logic are broadly agreed on, there are a number of various methods of fuzzy inference and defuzzification.
The fuzzy logic implementation in Knowledge Builder was developed with three objectives in mind; to provide comprehensive features, to maintain ease of use and to integrate seamlessly with the non fuzzy (crisp) Rules in Knowledge Builder.

 Fuzzy Logic
Fuzzy logic controls household appliances such as washing machines, which sense load size and detergent concentration and adjust their wash cycles accordingly, and refrigerators.
Fuzzy logic differs from classical logic in that statements are no longer fl or white, true or false, on or off.
Professor Zadeh's paper on fuzzy sets introduced the concept of a class with unsharp boundaries and marked the beginning of a new direction by providing a basis for a qualitative approach to the analysis of complex systems in which linguistic rather than numerical variables are employed to describe system behavior and performance.

 Fuzzy Multidimensional Logic
Fuzziness extends the concepts of probability to encompass partial events, each of which can now occur with a strength between 0 and 1, for example we now allow for the probability of a half (eaten) apple (FTV 0.5).
In fuzzy logic we rate each variable as a fuzzy truth value, giving 1 to the best option, 0 to the worst and proportionate in between (we could alternatively rate them with respect to a theoretical or practical minimum and maximum for the variable in question).
Fuzzy logic is just one of a number of non-standard logics that currently exist and which are used to cope with situations excluded from classical bivalent logic.

Another fuzzy rule from the table says that if our phase error is zero and our change in error is zero, then our output should be zero.

 APPLICATION OF FUZZY LOGIC IN DATA MINING   (Site not responding. Last check: )
Fuzzy logic bridges this gap and allows the use of qualitative/linguistic terms in formation of extraction rules.
Fuzzy logic was introduced by Dr. Zadeh of University of California/Berkley in early 1960's to provide a way of modeling the uncertainty of natural language.
The fuzzy rules were created by analyzing the actual data in specified cases of earthquakes, automobiles etc. A feature extraction was done on the data set to identify each kind of causes.

 Fuzzy logic tutorial.
Fuzzy logic is used in system control and analysis design, because it shortens the time for engineering development and sometimes, in the case of highly complex systems, is the only way to solve the problem.
Fuzzy logic control and analysis systems may be electro-mechanical in nature, or concerned only with data, for example economic data, in all cases guided by "If-Then rules" stated in human language.
It is based on fuzzy perceptions, fuzzy truths, fuzzy inferences, etc., all resulting in an averaged, summarized, normalized output, which is given by the human a precise number or decision value which he or she verbalizes, writes down or acts on.

 Fuzzy Logic: Q&A
But in a broader and much more significant sense, fuzzy logic is coextensive with the theory of fuzzy sets, that is, classes of objects in which the transition from membership to nonmembership is gradual rather than abrupt.
Fuzzy "if-then" rules are often employed to capture the imprecise modes of reasoning that play an essential role in the human ability to make decisions in uncertain and imprecise environments.
Fuzzy sets can be plotted in a discrete form or in a continuous representation, and any number of fuzzy sets can be plotted together.

 FAQ: Fuzzy Logic and Fuzzy Expert Systems 1/1 [Monthly posting] - [2] What is fuzzy logic?
Date: 15-APR-93 Fuzzy logic is a superset of conventional (Boolean) logic that has been extended to handle the concept of partial truth -- truth values between "completely true" and "completely false".
(Note: Lotfi, not Lofti, is the correct spelling of his name.) Zadeh says that rather than regarding fuzzy theory as a single theory, we should regard the process of ``fuzzification'' as a methodology to generalize ANY specific theory from a crisp (discrete) to a continuous (fuzzy) form (see "extension principle" in [2]).
Fuzzy Subsets: Just as there is a strong relationship between Boolean logic and the concept of a subset, there is a similar strong relationship between fuzzy logic and fuzzy subset theory.
