Exploratory Model Building
  Some instances of creative thinking require an agent to build and test
hypothetical theories. Such a reasoner needs to explore the space of not only
those situations that have occurred in the past, but also those that are
rationally conceivable. In this paper we present a formalism for exploring the
space of conceivable situation-models for those domains in which the knowledge
is primarily probabilistic in nature. The formalism seeks to construct
consistent, minimal, and desirable situation-descriptions by selecting suitable
domain-attributes and dependency relationships from the available domain
knowledge.
