Abstract : Cirrus is a tool for protocol analysis. Given an encoded protocol of a subject solving problems, it constructs a model that will produce the same protocol as the subject when it is applied to the same problems. In order to parameterize Cirrus for a task domain, the user must supply it with a problem space: a vocabulary of attributes and values for describing spaces, a set of primitive operators, and a set of macro-operators. Cirrus' model of the subject is a hierarchical plan that is designed to be executed by an agenda-based plan follower. In this paper, the philosophical and mathematical foundations of Cirrus are explored. Keywords: Cognitive psychology, Machine learning, Procedure induction, Computer programs.
