Methods and systems of integrating information include spatial representation of parameter values. In some embodiments, parameter values-are positioned along edges of an array and geometrical constructs based on the parameter positions are used to integrate the parameter values. In some embodiments, arrays of modules that correspond in their properties to attractor networks are used in combination with activity patterns that represent parameter values to integrate information. The methods and systems may be used to categorize objects into classes or concepts. For example, frequency agile radar emitters may be detected and/or classified using techniques described herein.
