Detection theory — Detection theory, or signal detection theory, is a means to quantify the ability to discern between signal and noise. According to the theory, there are a number of determiners of how a detecting system will detect a signal, and where its… … Wikipedia
Detection — In general, detection is the extraction of information from any clear or clouded ambient or otherwise accessible stream of information without neither support from the sender nor synchronization to the sender.In the history of radio… … Wikipedia
Signal processing — is an area of systems engineering, electrical engineering and applied mathematics that deals with operations on or analysis of signals, in either discrete or continuous time. Signals of interest can include sound, images, time varying measurement … Wikipedia
Decision theory — in economics, psychology, philosophy, mathematics, and statistics is concerned with identifying the values, uncertainties and other issues relevant in a given decision, its rationality, and the resulting optimal decision. It is closely related to … Wikipedia
Cultural consensus theory — supports a framework for the measurement and evaluation of beliefs as cultural; shared to some extent by a group of individuals. Cultural consensus models guide the aggregation of responses from individuals to estimate (1) the culturally… … Wikipedia
Signal noise — In science, and especially in physics and telecommunication, noise is fluctuations in and the addition of external factors to the stream of target information ( signal ) being received at a detector. In communications, it may be deliberate as for … Wikipedia
Theory of camouflage — The theoretical basis for camouflage is the underlying methodology used in by camouflage, whether natural or man made. The definition of camouflage involves concealment and obscurity , whether applied to the natural coloration of animals, or the… … Wikipedia
Estimation theory — is a branch of statistics and signal processing that deals with estimating the values of parameters based on measured/empirical data. The parameters describe an underlying physical setting in such a way that the value of the parameters affects… … Wikipedia
Information theory — Not to be confused with Information science. Information theory is a branch of applied mathematics and electrical engineering involving the quantification of information. Information theory was developed by Claude E. Shannon to find fundamental… … Wikipedia
Digital signal processing — (DSP) is concerned with the representation of discrete time signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. DSP includes… … Wikipedia
Signalling theory — Within evolutionary biology, signalling theory refers to a body of theoretical work examining communication between individuals. The central question is when animals with conflicting interests should be expected to communicate honestly .… … Wikipedia
