Related terms: → coalesce; → merge;

fuzz porz (#) Fr.: duvet, poils fins 1) Loose, light, fibrous, or → fluffy matter. Of unknown origin; cf. Du. voos "spongy, woolly." Porz "short fuzzy ends of fibers on the surface of cloth, any downy coating," of unknown etymology. |
fuzzification porzvâreš Fr.: fuzzification The first step carried out in a → fuzzy logic system during which a → crisp set of → input data are gathered and converted to a → fuzzy set using fuzzy → linguistic variables, fuzzy linguistic terms, and → membership functions. |
fuzzify pozvâridan Fr.: fuzzifier To convert a → crisp set to a → fuzzy set in a → fuzzy logic system. |
fuzziness porzvâri Fr.: The state or condition of being → fuzzy. |
fuzzy porzvâr Fr.: flou, crépu 1) Of the nature of or resembling → fuzz. From → fuzz + -y adj. suffix, from O.E. -ig, cognate with L. -icus, → -ic. Porzvâr "resembling fuzz," from porz, → fuzz, + -var, a suffix of possession, similarity, and aptitude (e.g., omidvâr, sezâvâr, sugvâr, šâhvâr, gušvâr), → -oid. |

fuzzy inferencing darbord-e porzvâr Fr.: A process used in a → fuzzy logic system where the → truth value for the premise of each rule is computed and applied to the conclusion part of each rule. This results in one fuzzy set to be assigned to each output variable for each rule. |
fuzzy logic guyik-e porzvâr Fr.: logic flou A mathematical logic that recognizes more than simple → true and → false → propositions. With fuzzy logic, propositions can be represented with degrees of truthfulness and falsehood. In this system, → truth values are → fuzzy sets without sharp boundaries (→ crisp set) in contrast with → classical logic. Fuzzy logic is applied to a wide range of problems including: industrial control, domestic goods, decision making, robotics, intelligent machines, and image processing in medicine. |
