Learning Hierarchical Skills from Problem Solutions Using Means-Ends Analysis
نویسندگان
چکیده
Humans acquire skills in different ways, one of which involves learning from worked-out solutions to problems. In this paper, we present an extension to the ICARUS cognitive architecture that lets it acquire complex hierarchical skills in this manner. Unlike previous work on this topic, our approach relies on an existing architectural mechanism, means-ends analysis, to explain steps in the problem solution and to learn new structures. We illustrate this method in the domains of multi-column subtraction and football, after which we discuss related work and consider directions for future research in this area.

Acquisition of Hierarchical Reactive Skills in a Unified Cognitive Architecture Action Editor: Ron Sun
In this paper, we review ICARUS, a cognitive architecture that utilizes hierarchical skills and concepts for reactive execution in physical environments. In addition, we present two extensions to the framework. The first involves the incorporation of means-ends analysis, which lets the system compose known skills to solve novel problems. The second involves the storage of new skills that are ba...

In this document, we introduce Icarus, a cognitive architecture for physical agents that utilizes hierarchical concepts and skills for inference, execution, and problem solving. We first review the assumptions typically made in work on cognitive architectures and explain how Icarus differs from earlier candidates. After this, we present the framework’s approach to conceptual inference, its mech...
متن کاملThe Efficacy of Occupational Therapy Intervention in Visual-Spatial and Visual Analysis Skills Development among Children with Learning Disorders
Objectives: The visual-motor skill is one of the major factors in the learning process. Visual-spatial and visual analysis skills are components of the visual motor skill. Any deficiency in Visual-Motor skills and their components often causes problem in writing and learning processes in children. The aim of this study was to investigate the effect of occupational therapy (O.T.) intervention on...
متن کاملLearning by Analogy: Formulating and Generalizing Plans from Past Experience
Analogical reasoning is a powerful mechanism for exploiting past experience in planning and problem solving. This paper outlines a theory of analogical problem solving based on an extension to means-ends analysis. An analogical transformation process is developed to extract knowledge from past successful problem solving situations that bear strong similarity to the current problem. Then, the in...
