Redefining the Rules: Providing Race Models with a Connectionist Learning Rule

In this paper, we describe the Parallel Race Network (PRN), a race model with the ability to learn stimulus–response associations using a formal framework that is very similar to the one used by the traditional connectionist networks. The PRN assumes that the connections represent abstract units of time rather than strengths of association. Consequently, the connections in the network indicate how rapidly the information should be sent to an output unit. The decision is based on a race between the outputs. To make learning functional and autonomous, the Delta rule was modified to fit the time-based assumption of the PRN. Finally, the PRN is used to simulate an identification task and the implications of its mode of representation are discussed.
