 DictionaryExample entry: 
word (similar words) [hyperlinks]definition. 
delta-rule [text]see text.activity level [text, text]the weighed sum of the inputs into a neuron.AI system (Artificial Intelligence system) [text]a man-made system that is meant to behave intelligently.anti-Hebbian rule [text]the weight between neurons is decreased when the neuron fires. See 
text.auto-associative memory [text]when some learning rules operate they adapt the weights so that for a given input the output matches a "teacher"
signal. Auto-associative systems assume the "teacher" is the same as the input. These systems are used to correct
data.binary [text]a number system with only two digits, 0 and 1.biological computation [text]the processing carried out in the brain.Boltzmann machine [text, text, text]see text.chaos theory [text]simple rules can give rise to very complex systems. It is impossible to accurately predict the behaviour of such
systems unless its components and rules are known, perfectly.cortex [text]the brain is divided into many sections, this is the outer layer of the brain.CPU (Central Processing Unit) [text]this is the part of the computer that runs the programs.current of injury [text]the name given to the current a neuron emits after it has been injured.energy relaxation [text, text]see text.excitory [text]a connection which increases the activity level of a neuron.expert system [text, text, text]a particular type of AI system that uses a knowledge base and a set of instructions to answer questions.feedback [text]where information at a letter part of a system can effect information in an earlier part of the system.generalised delta-rule [text]see text.heat buildup [text]the resistance in any electrical component causes electrical energy to turn into heat. This may cause damage if the
temperature becomes too high.Hebbian rule (Hebb's law) [text, text, text]see text.hidden layer [text, text]see text.Hopfield's principal [text]energy relaxation. See text.inhibitory [text]a connection which decreases the activity level of a neuron.input layer [text, text]see text.input-output function [text, text, text]the process through which the activity level of a neuron goes before being sent as a signal to other neurons.linear [text, text]see text.main-frames [text]large, powerful computers that allow more than one user to access them at the same time.microprocessor [text]a chip that contains an entire functional unit of a computer.minicomputer [text]smaller, cheaper machines than main-frames but limited to more specific tasks. Digital Equipment Corp. pioneered
these and this led to the introduction of computers into technical and scientific markets.neural network (neural net,network,net) [text, text, text]a circuit or simulation built to model or simulate the way the brain works.output layer [text, text]see text.phonemes [text]the units of speech out of which all words are made.RAM (Random Access Memory) [text]a memory storage device for computers built on a chip.RAM, dynamic [text]this uses capacitors and so the memory has to be "refreshed" every so often, this takes up some of the computer's
time.RAM, static [text]this uses transistors and so does not have to be "refreshed" and therefore doesn't take up the computer's
time.sigmoid [text, 
text]see text.supercomputer [text, text]very large,powerful computers used for large amounts of processing.synapse [text]the minute gap between two "joined" neurons through which chemical signals from the neurons pass.three-dimensional energy surface [text]a graph where the x and y axis represent the states of the circuit and the z axis represents the "energy" of the
circuit.threshold [text]see text.weight [text, text, text]the name given to the amount that a signal is multiplied before being given to a neuron.
