Nettalk
| Глоссарий по искусственному интеллекту |
Nettalk, created in 1978, is a classic example of a training multilayer perceptron network that was used to study the conversion of text to spoken words. the network converted the text input into a series of feature vectors, which were then mapped into a sequence of phonemes and stress markers. when the system was trained on 1024 words extracted from a child`s speech, it was 95 percent accurate in producing the correct phoneme, and achieved a 78 percent accuracy on a second set of about 450 words that were not in the training set. the network was fairly robust to variations in the node weights and required a much smaller storage space than comparable dictionary lookup programs. see also: perceptron, neural network.

Multilayer, английский
Многослойный; многоуровневый
Perceptron, английский
- Перцептрон (обучаемый распознающий робот)
- A simple pattern recognition device that was the precursor of modern neural nets. the original perceptron took a weighted sum of a set of inputs, added a constant "bias" or "offset" and returned a zero or one, depending on whether or not the sum was above or below a threshold. perceptron-type circuits underlie modern neural nets.
- A mechanical device developed in the 1950`s by rosenblatt for deciding (->decision) among, and to a limited degree for the recognition and learning of patterns which are defined by relations among a multitude of stimuli in its input. performance
Conversion, английский
- Transformation of a forest from one forest type to another, favoring a particular species or group of species through practices such as cutting, planting, or weeding.
- The wrongful assumption of ownership over the goods or personal property belonging to another
- Пересчет
- Преобразование, переход
- The process of changing one thing into another the conversion of nutrients into tissue
- Модернизация (напр., станка)

- Reducing a vessel by a deck, thereby converting a line-of-battle ship into a frigate, or a crank three-decker into a good two-decker; or a serviceable vessel into a hulk, resembling a prison or dungeon, internally and externally, as much as possible.
- An action by which a subscription (the source subscription) is replaced by a new subscription, both owned by the same billing account, along a preconfigured conversion path. the source subscription is canceled and the destination subscription is the new subscription.
- An action taken by a visitor to your public web site that results in a desired customer response, such as requesting more information or signing up for a newsletter.
- The process of changing from one form or format to another; where information is concerned, a changeover that affects form but not substance. types of conversion include data (changing the way information is represented), file (changing a file from one format to another), hardware (changing all or part of a computer system), media (transferring data from one storage media to another), software (changing a program designed for one platform so that it runs on another), and system (changing from one operating system to another).
- In the context of securities, refers to the exchange of a convertible security such as a bond into stock. in the context of mutual funds, refers to the free exchange of mutual fund shares from one fund to another in a single family.
- Изменение
- Energy shows itself in numerous ways, with transformations from one type to another called energy conversions. for example, kinetic energy in wind fl ows is captured as rotating shaft work further converted to electricity; solar light is converted into electricity by photovoltaic cells. also, electric currents of given characteristics (e.g., direct/ alternating, voltage level) are converted to currents with other characteristics. a converter is the equipment used to realize the conversion.
- When a user completes a desired action on a website. examples of conversions include:
- A conversion is any desired action taken on a website like a purchase, the completion of a contact form, and so on. unique conversions can be set up and tracked in google analytics for a website so one can see how many times these actions have been taken.
Comparable, английский

Netica, английский
Netica is a commercial system for building, manipulating, and implementing expert systems based on the belief network and influence diagrams. the networks can be complied into a form suitable for fast reasoning, and can accept data in a wide variety of formats. these networks can be used to find optimal decisions, and can be used to construct conditional plans. see also: http://www.norsys.com/
Bias input, английский
Neural network models often allow for a "bias" term in each node. this is a constant term that is added to the sum of the weighted inputs. it acts in the same fashion as an intercept in a linear regression or an offset in a generalized linear model, letting the output of the node float to a value other than zero at the origin (when all the inputs are zero.) this can also be represented in a neural network by a common input to all nodes that is always set to one.
