Abstract
An electronic adaptive recognizing device which includes an input store having a number of storage locations for receiving an input signal, and a number of addressable stores each having one or more address lines connected to a number of the input store locations in either a random way or one determined by the input signal. The contents of the input store specify addressable store locations at which words of at least one bit are stored. Structure is provided for deriving a common value based on the words stored at the specified addressable store locations and for calculating a corrected value based on a received value and the common value. An updated value is applied, dependent on the corrected value, to each of the specified addressable store locations so that the common value is adapted to changes in the dependence of the received value on the input signal and so that the device can output an appropriate corrected value for a given input signal.
