Exploring the minimal dynamics of behavioural preference.
飯塚博幸 · 2008
A preference is not located anywhere in the agent's cognitive architecture, but it is rather a constraining of behaviour which is in turn shaped by behaviour. Based on this idea, a minimal model of behavioural preference is proposed. A simulated mobile agent is modelled with a plastic neurocontroller, which holds two separate high dimensional homeostatic boxes in the space of neural dynamics. A evolutionary algorithm is used for creating an association between the boxes and the performance of two different phototactic behaviours. After evolution, the agent's performance exhibits some important aspects of behavioural preferences such as durability and transitions. A series of studies demonstrates how these properties arise through the mutual constraining of internal and external dynamics.
