Measuring Change and Coherence in Evaluating Potential Change in View

In changing your view, you must balance the amount of change involved against the improvement in explanatory coherence resulting from the change. Even if change and improvement in coherence are measured by simply counting, there can be no general requirement that the number of modified items (added or subtracted) be no greater than the number of new explanatory and implications links. The relation between conservatism and coherence is mroe complex than that

Planning-Based Integrated Decision Support Systems

This paper describes a system that uses AI planning and representation techniques as the core of a decision support system. * The planning technology is supplemented with other AI and non-AI technologies. The overall system and initial application domain, military operations planning, are described first. We then describe the integration of SIPE-2, a generative planning system, with three independently-developed AI systems: a temporal reasoning engine, a case-based force selection module, a system for scheduling and capacity analysis. 1 INTRODUCTION In tackling a real-world problem with an AI solution, it is not uncommon to find that a single AI system fails to meet all the problem requirements. In some cases, existing software can be integrated (or must be used) with the AI solution; or the AI system must be altered to fit the new problem (e.g., with a customized user interface); or new software must be added to round out the capabilities of the single system. In this paper, we rep..

Learning Analytics Goes to School : A Collaborative Approach to Improving Education

Learning Analytics Goes to School presents a framework for engaging in education research and improving education practice through the use of newly available data sources and analytical approaches. The application of data-intensive research techniques to understanding and improving learning environments has been growing at a rapid pace. In this book, three leading researchers convey lessons from their own experiences--and the current state of the art in educational data mining and learning analytics more generally--by providing an explicit set of tools and processes for engaging in collaborative data-intensive improvement.Preface ; 1 : Introduction ; 2 : Data Used in Educational Data-Intensive Research ; 3 : Methods Used in Educational Data-Intensive Research ; 4 : Legal and Ethical Issues in Using Educational Data ; 5 : Foundations of Collaborative Applications of Educational Data Mining and Learning Analytics ; 6 : Supporting Conditions for Collaborative Data-Intensive Improvement ; 7 : Five Phases of Collaborative Data-Intensive Improvement ; 8 : Lessons Learned and Prospects for the Future ; Glossary ; Inde

SOCAP: System for Operations Crisis Action Planning

In this paper, we report on our past and recent experiences in applying an AI generative planning system, called System for Interactive Planning and Execution (SIPE-2), to the problem of generating crisis action operations plans in a joint military domain * . We describe our motivation for selecting a generative planner, the application itself (including the second Integrated Feasibility Demonstration, IFD-2) , and the lessons we learned in creating it. We also report on the applied research we performed to address the lessons learned in IFD-2. This involved integrating the generative planner with several complementary technologies that were available through the Planning Initiative (PI): a temporal reasoner, a case-based reasoner, and the capacity analysis component of a scheduling system. These technology integration experiments (TIEs) were executed within the Common Prototyping Environment (CPE). We discuss both the unique characteristics of each TIE and the general features that ..
