Belief change with uncertain action histories

摘要: We consider the iterated belief change that occurs following an alternating sequence of actions and observations. At each instant, agent has beliefs about have occurred as well resulting state world. represent such problems by a ranking functions, so assigns quantitative plausibility value to every action at point in time. The formalism is able fallible belief, erroneous perception, exogenous actions, failed actions. illustrate our framework generalization several existing approaches change, it appropriately captures non-elementary interaction between update revision.
