The Interactive Activation and Competition Network Structure

• consists of a number of competitive pools of units

• each unit represents some micro-hypothesis or feature

• units within each competitive pool are mutually exclusive features and are interconnected with negative weights

• between the pools positive weights indicate features or micro-hypotheses which are consistent

• when the network is cycled, units connected by positive weights to active units become more active, while units connected by negative weights to active units are inhibited

• connections are, in general, bidirectional making the network interactive
