This paper describes the integration of several cognitively inspired anticipation
and anticipatory learning mechanisms in an autonomous agent architecture,
the Learning Intelligent Distribution Agent (LIDA) system. We provide computational
mechanisms and experimental simulations for variants of payoff, state, and
sensorial anticipatory mechanisms. The payoff anticipatory mechanism in
LIDA is implicitly realized by the action selection dynamics of LIDA’s
decision making component, and is enhanced by importance and discrimination
factors. A description of a non-routine problem solving algorithm is presented
as a form of state anticipatory mechanism. A technique for action driven
sensational and attentional biasing similar to a preafferent signal and
preparatory attention is offered as a viable sensorial anticipatory mechanism.
We also present an automatization mechanism coupled with an associated deautomatization
procedure, and an instructionalist based procedural learning algorithm as
forms of implicit and explicit anticipatory learning mechanisms. |
