In this paper we introduce the use of map-seeking circuits for auditory pattern detection and classification. A map-seeking circuit is a signal processing structure used to detect a desired feature in a mixture by iteratively transforming, superposing, and comparing the composite mixture with a pattern template. The result is a mapping between the template and the position of the matched feature in the mixture. The iterative detection process is inspired by the neural connections in the human

A particularly important feature of map-seeking classification is that the search operates on an additive superposition of allowable transformations of the desired feature vector, giving a linear increase in computation with increasing image complexity, rather than a brute-force feature detection that increases in computation geometrically.
