Learning To See Analogies: A Connectionist Exploration, Douglas S. Blank Dec 1997

Learning To See Analogies: A Connectionist Exploration, Douglas S. Blank

Computer Science Faculty Research and Scholarship

The goal of this dissertation is to integrate learning and analogy-making. Although learning and analogy-making both have long histories as active areas of research in cognitive science, not enough attention has been given to the ways in which they may interact. To that end, this project focuses on developing a computer program, called Analogator, that learns to make analogies by seeing examples of many different analogy problems and their solutions. That is, it learns to make analogies by analogy. This approach stands in contrast to most existing computational models of analogy in which particular analogical mechanisms are assumed a priori ...


Trends. Some Security Lessons From Kyoto, Editor Dec 1997

Trends. Some Security Lessons From Kyoto, Editor

International Bulletin of Political Psychology

The author discusses how "the environment" is no longer a fringe Issue championed by starry-eyed dreamers and psychodynamic deviants, and perennial misfits who have little understanding of or orientation to reality. In fact, the relevance of "the environment" for policies of political security has become quite significant.


Public Participation Program Development: An Analysis Of Public Participation In The Water Industry, Marcia Lynne Holmberg Dec 1997

Public Participation Program Development: An Analysis Of Public Participation In The Water Industry, Marcia Lynne Holmberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of public participation is a distinct, but yet unpolished facet within the public relations industry. While the purpose of and need for public participation are becoming increasingly clear, many remain unaware or unconvinced of its advantages. Likewise, even among those who endorse the necessity of public participation, its methods and strategies continue to be a mystery to most.

One industry, in particular, that has recognized and embraced the benefits of conducting public participation is the water utility industry. The purpose of this thesis is to 1) crystallize the understanding of why public participation is a necessary and advantageous ...


Factors Influencing Wetland Use By Canada Geese, David E. Naugle, Jeffrey S. Gleason, Jonathan A. Jenks, Kenneth E. Higgins, Paul W. Mammenga, Sarah M. Nusser Dec 1997

Factors Influencing Wetland Use By Canada Geese, David E. Naugle, Jeffrey S. Gleason, Jonathan A. Jenks, Kenneth E. Higgins, Paul W. Mammenga, Sarah M. Nusser

Statistics Publications

Seasonal and semi-permanent wetlands in eastern South Dakota were surveyed in 1995 and 1996 to identify habitat characteristics influencing wetland use by Canada geese (Branta canadensis maxima). Position of a wetland within the landscape and its area were important landscape-scale features influencing wetland use by geese. Our delineation of potential Canada goose habitat using a wetland geographic information system indicated that distribution and area of semi-permanent wetlands likely limit Canada goose occurrence in regions outside the Prairie Coteau. Periodicity in hydrologic cycles within landscapes also may influence goose use of wetlands in eastern South Dakota.

Almost Everybody Disagrees Almost All The Time: The Genericity Of Weakly Merging Nowhere, Ronald I. Miller, Chris William Sanchirico Nov 1997

Almost Everybody Disagrees Almost All The Time: The Genericity Of Weakly Merging Nowhere, Ronald I. Miller, Chris William Sanchirico

Faculty Scholarship at Penn Law

Suppose we randomly pull two agents from a population and ask them to observe an unfolding, infinite sequence of zeros and ones. If each agent starts with a prior belief about the true sequence and updates this belief on revelation of successive observations, what is the chance that the two agents will come to agree on the likelihood that the next draw is a one? In this paper we show that there is no chance. More formally, we show that under a very unrestrictive definition of what it means to draw priors “randomly,” the probability that two priors have any ...

Sampling Schemes For Policy Analyses Using Computer Simulation Experiments, Alicia L. Carriquiry, F. Jay Breidt, P. G. Lakshminarayan Nov 1997

Sampling Schemes For Policy Analyses Using Computer Simulation Experiments, Alicia L. Carriquiry, F. Jay Breidt, P. G. Lakshminarayan

CARD Working Papers

Evaluating the environmental and Economic impacts of agricultural policies is not a simple task. A systematic approach to evaluation would include the effect of policy-dependent factors (such as tillage practices, crop rotations, and chemical use) as well as the effect of policy independent covariates (such as weather, topography, and soil attributes) on response variables (such as amount of soil eroded or chemical leached into the groundwater). For comparison purposes, the effects of these input combinations on the response variable would have to be assessed under competing policy scenarios. Because the number of input combinations is high in most problems, and ...


Simulation Study Of Learning Automata Games In Automated Highway Systems, Cem Unsal, Pushkin Kachroo, John S. Bay Nov 1997

Simulation Study Of Learning Automata Games In Automated Highway Systems, Cem Unsal, Pushkin Kachroo, John S. Bay

Electrical and Computer Engineering Faculty Publications

One of the most important issues in Automated Highway System (AHS) deployment is intelligent vehicle control. While the technology to safely maneuver vehicles exists, the problem of making intelligent decisions to improve a single vehicle’s travel time and safety while optimizing the overall traffic flow is still a stumbling block. We propose an artificial intelligence technique called stochastic learning automata to design an intelligent vehicle path controller. Using the information obtained by on-board sensors and local communication modules, two automata are capable of learning the best possible (lateral and longitudinal) actions to avoid collisions. This learning method is capable ...


The National Pilot Program Integrated Modeling System: Environmental Baseline Assumptions And Results For The Apex Model, Philip W. Gassmann Nov 1997

The National Pilot Program Integrated Modeling System: Environmental Baseline Assumptions And Results For The Apex Model, Philip W. Gassmann

CARD Staff Reports

This paper presents the underlying assumptions and results for the Agricultural Policy/Environmental eXtender (APEX) model, which was applied within an integrated modeling system for the National Polio Program (NPP) environmental baseline simulations for the Upper North Bosque River Watershed area in Texas. The system consists of an economic model linked to an environmental component comprising the field-scale APEX and watershed-scale Soil Water Assessment Tool (SWAT) models. The results are edge-of-field environmental indicators obtained from the APEX model.

Calibrated Learning And Correlated Equilibrium, Dean P. Foster, Rakesh V. Vohra Oct 1997

Calibrated Learning And Correlated Equilibrium, Dean P. Foster, Rakesh V. Vohra

Statistics Papers

Suppose two players repeatedly meet each other to play a game where:

1. each uses a learning rule with the property that it is a calibrated forecast of the other's plays, and

2. each plays a myopic best response to this forecast distribution.

Then, the limit points of the sequence of plays are correlated equilibria. In fact, for each correlated equilibrium there is some calibrated learning rule that the players can use which results in their playing this correlated equilibrium in the limit. Thus, the statistical concept of a calibration is strongly related to the game theoretic concept of ...

From Contemporary Workflow Process Automation To Adaptive And Dynamic Work Activity Coordination And Collaboration, Amit P. Sheth Sep 1997

From Contemporary Workflow Process Automation To Adaptive And Dynamic Work Activity Coordination And Collaboration, Amit P. Sheth

Kno.e.sis Publications

The article outlines a research agenda for researchers in the area of workflow. We believe that today's workflow systems should evolve to what is termed as work coordination and collaboration systems (WCCSs). A WCCS will: (a) adapt to various changes in the organization (including its interactions with external organizations) and the organizational processes by being able to change the process definitions as well as change the processes and component activities while they are being enacted or executed; and (b) support a unified framework for managing coordination, collaboration, and information based decision making activities that naturally occur as part of ...
