Mahalanobis distance
| Глоссарий по искусственному интеллекту |
Mahalanobis distances are a generalization of classic euclidean distances that allow that changes in some directions are harder or more "expensive" than changes in other directions. the relative "cost" of the differences are summarized in a weight matrix w, and the distance is calculated as the square root of (x-y)`w(xy), where x and y are the feature vectors of the two objects being compared. see also: manhattan distance, metric,, ordinary least squares.

- The light-subject distance not only controls fall-off, but also shadow quality and the effective size of the light. see: throw.
- Расстояние
- The run which a ship has made upon the log-board. in speaking of double stars, it is the space separating the centres of the two stars, expressed in seconds of arc. (see lunar distances.)

Distance acuity, английский
The eye’s ability to distinguish an object’s shape and detail at a far distance, such as 20 feet (6 meters).
Distance along the edge that this deviation occurs., английский
Distance amplitude correction, английский
Compensation of gain as a function of time for difference in amplitude of reflections from equal reflectors at different sound travel distances. refers also to compensation by electronic means such as swept gain, time corrected gain, time variable gain and sensitivity time control.
Distance amplitude correction (ut), английский
Compensation for variance in amplitude from equal reflectors at different sound travel distances. the abbreviation is dac. also used to denote electronic change of amplification to provide equal amplitude from equal reflectors at different sound travel distances. other designations for this electronic change of amplification are swept gain (sg), time corrected gain (tcg), time variable gain (tvg) and sensitivity time control (stc).
Distance block, английский
A wood block which separates two components from each other at a fixed distance.
Distance blocks, английский
Distance constant, английский
The passage of air necessary over a wind speed sensor to cause the sensor to respond to 63% of a step function change in wind speed.

Generalization, английский
- N амер. ге- нерализация, абстрактизация, расширение; обобщение; over~ сверхгенерализация
- Обобщение
- Inferring general principles from recurring events. so if we see x at the bus stop every tuesday, we generalize that he is always there at that time. of course, one day he isn’t….
- An objective conclusion
- An objective conclusion a perception based on observations (for example, “americans are usually friendly”). different from a stereotype (for example, “all americans are friendly”)
Directions, английский
- Directions for use (on a bottle of medicine, etc.) instructions showing how to use something and how much of it to use
- Раскреплённый связями в двух взаимно перпендикулярных направлениях
- In the maps application, instructions for how to get from one location to another, either driving or walking.
Differences, английский

Linked inference rules, английский
Linked inference rules relax the syntactic constraints of ordinary inference rules by allowing link clauses to serve as bridges between clauses that initiate inferences and clauses that complete inferences. ur-resolution, hyperresolution, and paramodulation can all be extended by allowing link clauses to link the nucleus with the satellite clauses. see also: hypermodulation, paramodulation, ur-resolution..
Demon procedures, английский
Many frame-based and object-based systems have a collection of associated automatic procedures, sometimes called demon procedures, such as "when-requested" procedures or "when-read" procedures. these refer to procedures that are automatically triggered when a particular event occurs. the procedures can be generic to a type of object or specific to a particular instance. a more prosaic example would be a program that watches a mail file and notifies the recipient that new mail has arrived. de morgan`s laws de morgan`s laws are two standard relationships in logic: 1. the negation of a conjunction is the disjunction of the negations; and 2. the negation of a disjunction is the conjunction of the negations. dempster`s rule of combination dempster`s rule of combination provides a method for combining different belief functions over the same frame of discernment. the core for a set from a combination of two belief functions bell and bel is computed from the cores of the two functions. the product set of the two cores is first computed, and values associated
