Fuzzy entropy
| Глоссарий по искусственному интеллекту |
Fuzzy entropy is a measure of the fuzziness of a set. for a set a and its fuzzy complement b, fuzzy entropy is the ratio of the underlap of a b to the overlap of a b. in classical (crisp) sets, this value is, by definition, 0, since the cardinality of a b is defined to be 0 and the cardinality of a b is similarly defined to be 1 (for a non-empty universe). the larger this value is, for a given set of elements, the fuzzier the set a (and b) becomes. see also: fuzzy set theory, underlap, overlap.

Entropy, английский
- Энтропия
- Entropy is a measure of the disorganization or information within a system. the entropy is lowest when there is a certain outcome or state, and highest when all the possible states are equally likely. for a discrete system with k states, it is defined as where pi is the probability of being in state i. see also: fuzzy entropy, maximum entropy principle.
- ->statistical entropy, a measure of variation, dispersion or diversity; ->thermodynamic entropy, a measure of unusable energy. the similarity between the two types of entropy is merely formal in that both are expressed as the logarithm of a probability. t
- The level of disorder in a system.
- From the second law of thermodynamics, the measure of disorder in a system.
- A measure of the level of disorder or randomness in a closed system. it can be thought of either in the sense of thermodynamic/metabolic processes or the increasing molecular disorder in a structure. it can be thought of as the same process by which erosion occurs when soil is exposed to rain and wind.

Fuzzy art, английский
A network that synthesizes adaptive resonance theory (art) and fuzzy logic. see also: ftp:://ftp.sas.com/pub/neural/faq2.html, http://www.wi.leidenuniv.nl/art/.
Fuzzy artmap, английский
A supervised fuzzy art network. see also: ftp:://ftp.sas.com/pub/neural/faq2.html, http://www.wi.leidenuniv.nl/art/. fuzzy associative mmemory (fam) a fuzzy function, or model, that takes a k-dimensional fuzzy input and produces a 1-dimension fuzzy output. comparable to a regression model or a neural network. the model can learn (estimate) from data or have its parameters set in some other fashion, e.g., by the model designer.

Fuzzy count, английский
A measure of the size of a fuzzy set a and defined as the sum of all membership values in a. it is the fuzzy generalization of a classic set notion of cardinality, or size of a set.
Fuzzy cozmplement, английский
The fuzzy complement of a fuzzy set is a fuzzy set whose membership functions are the complements of the original set (i.e., 1-m(a,x) where x are the elements in the original fuzzy set a).

Fuzzy grouping, английский
In integration services, a data cleaning methodology that examines values in a dataset and identifies groups of related data rows and the one data row that is the canonical representation of the group.

Superimposition fraud, английский
Fraud detection is a very active area in data mining. superimposition frauds are methods to commit fraud by piggy-backing on a legitimate account. one example would be the practice of "shoulder surfing" to learn pin numbers or credit card numbers. once this information has been obtained, the thief will attempt to exploit it quickly and obtain goods or money. a fraud detection system needs to detect changes quickly from normal behavior. data mining is used to discover these patterns.
Fuzzyclips, английский
- Fuzzyclips is an enhanced version of c language integrated production system (clips) developed at the national research council of canada that allows the implementation of fuzzy expert systems. it enables domain experts to express rules using their own fuzzy terms. it allows any mix of fuzzy and normal terms, numeric-comparison logic controls, and uncertainties in the rule and facts. fuzzy sets and relations deal with fuzziness in approximate reasoning, while certainty factors for rules and facts manipulate the uncertainty. the use of the above modifications is optional and existing clips programs still execute correctly. see also: c language integrated production system, http://ai iit.nrc.ca/fuzzy/fuzzy.html. fuzzy cognitive map (fcm) a graph with signed and directed arcs between nodes. the arc from node i to node j is an indicator of the influence of node i on node j. likewise, the arc from j to i is an indicator of the influence of node j on node i. these arcs do not need to be symmetric. when the nodes are initialized to some state, repeated application of the connection matrix derived from the graph can be used to determine the evolution of the system and any fixed points or limit cycles.
