Abstract

Statitsical relational models have been successfully used to model
static probabilistic relationships between the entities of the domain.
In this talk, we illustrate their use in a dynamic decison-theoretic
setting where the task is to assist a user by inferring his intentional
structure and taking appropriate assistive actions. We show that the
statistical relational models can be used to succintly express the
system's prior knowledge about the user's goal-subgoal structure and
tune it with experience. As the system is better able to predict the
user's goals, it improves the effectiveness of its assistance. We show
through experiments that both the hierarchical structure of the goals
and the parameter sharing facilitated by relational models significantly
improve the learning speed.
