Generating Decision Structures and Causal Explanations for Decision Making
Spencer Star

TL;DR
This paper explores how to generate structured decision problems and causal explanations from unstructured knowledge bases for autonomous agents, proposing causal constraints to improve efficiency and tractability.
Contribution
It introduces causal theories for deterministic and indeterministic worlds and demonstrates their use in generating explanations more efficiently.
Findings
Causal constraints improve explanation generation efficiency
The problem of generating decision structures is intractable without constraints
Proposed causal theories help in structuring explanations for faulty plans
Abstract
This paper examines two related problems that are central to developing an autonomous decision-making agent, such as a robot. Both problems require generating structured representafions from a database of unstructured declarative knowledge that includes many facts and rules that are irrelevant in the problem context. The first problem is how to generate a well structured decision problem from such a database. The second problem is how to generate, from the same database, a well-structured explanation of why some possible world occurred. In this paper it is shown that the problem of generating the appropriate decision structure or explanation is intractable without introducing further constraints on the knowledge in the database. The paper proposes that the problem search space can be constrained by adding knowledge to the database about causal relafions between events. In order to…
