A

abstraction
Generalisation, ignoring or hiding details.
accelerator
Additional hardware to perform some function faster than is possible in software running on the normal CPU.
Adaline
Name given by Widrow to adaptive linear neurons, that is neurons (see McCulloch-Pitts) which learn using the Widrow-Huff Delta Rule. See also Madaline.
adaptive
Adaptive neural networks classify patterns. Input data similar to previously seen patterns are classified as one of them. Patterns not similar to previous ones have a new class of patterns created for them.
adaptive learning
(Or "Hebbian learning") Learning where a system programs itself by adjusting weights or strengths until it produces the desired output.
adaptive learning rate
In artificial neural networks, training time of some networks can be decreased by the use of an adaptive learning rate which attempts to keep the learning step size as large as possible while keeping learning stable. The learning rate is made responsive to the complexity of the local error surface.
AI
artificial intelligence
AI-complete
A term used to describe problems or subproblems in artificial intelligence, to indicate that the solution presupposes a solution to the "strong AI problem" (that is, the synthesis of a human-level intelligence). A problem that is AI-complete is, in other words, just too hard.
algorithm
A detailed sequence of actions to perform to accomplish some task. Named after an Iranian mathematician, Al-Khawarizmi.
American National Standards Institute
(ANSI) The US government body responsible for approving US standards in many areas, including computers and communications.
American Standard Code for Information Interchange
The predominant character set encoding of present-day computers. The modern version uses seven bits for each character, whereas most earlier codes (including an early version of ASCII) used fewer.
ANSI
American National Standards Institute
Application Program Interface
The interface (calling conventions) by which an application program accesses operating system and other services.
artificial intelligence
(AI) The subfield of computer science concerned with the concepts and methods of symbolic inference by computer and symbolic knowledge representation for use in making inferences. AI can be seen as an attempt to model aspects of human thought on computers. It is also sometimes defined as trying to solve by computer any problem that a human can solve faster.
artificial life
(a-life) The study of synthetic systems which behave like natural living systems in some way. Artificial Life complements the traditional biological sciences concerned with the analysis of living organisms by attempting to create lifelike behaviours within computers and other artificial media.
artificial neural network
(ANN) A man-made neural network as opposed to a biological one (a brain).
ASCII
American Standard Code for Information Interchange
associative memory
content addresable memory
automation
Automatic, as opposed to human, operation or control of a process, equipment or a system; or the techniques and equipment used to achieve this. Most often applied to computer (or at least electronic) control of a manufacturing process.
automaton
(Plural automata) A machine, robot, or formal system designed to follow a precise sequence of instructions.
axiom
A well-formed formula which is taken to be true without proof in the construction of a theory.
axon
the connection to the output of a neuron.
