The Governor Architecture: Avoiding Catastrophic Forgetting In Robot Learning, Jeremy Strober, Lisa Meeden, Doug Blank

Computer Science Faculty Research and Scholarship

The governor architecture is a new method for avoiding catatrophic forgetting in neural networks that is particularly useful in online robot learn- ing. The governor architecture uses a categorizer to identify events and excise long sequences of repetitive data that cause catastrophic forgetting in neural networks trained on robot-based tasks. We examine the performance of several variations of the governor architecture on a number of re- lated localization tasks using a simulated robot. The results show that governed networks perform far better than ungoverned networks. Governored networks are able to reliably and robustly prevent catastrophic forgetting in robot learning tasks.

What Effect Does Spyware Have On Consumer Trust, And Will Its Use Ever Be Acceptable?, James Anthony Hatton

The Corinthian

Trust literature has been thoroughly developed in the field of Information Systems. However, recent innovations in broadband networks and the growing popularity of the Internet has brought rise to software called spyware - a program that employs a user's Internet connection in the background without the user's knowledge or explicit permission. This study attempts to analyze spyware and explore the nature of its effect on consumer trust. Additionally, the research examines what controls, if any may make the use of spyware acceptable to the consumer.

Cooperative Game Theory Within Multi-Agent Systems For Systems Scheduling, Derek Messie, Jae C. Oh

Electrical Engineering and Computer Science - All Scholarship

Research concerning organization and coordination within multi-agent systems continues to draw from a variety of architectures and methodologies. The work presented in this paper combines techniques from game theory and multi-agent systems to produce self-organizing, polymorphic, lightweight, embedded agents for systems scheduling within a large-scale real-time systems environment. Results show how this approach is used to experimentally produce optimum real-time scheduling through the emergent behavior of thousands of agents. These results are obtained using a SWARM simulation of systems scheduling within a High Energy Physics experiment consisting of 2500 digital signal processors.

Age Differences In Central (Semantic) And Peripheral Processing: The Importance Of Considering Both Response Times And Errors, Philip A. Allen, Martin D. Murphy, Miron Kaufman, Karen E. Groth, Ana Begovic

Physics Faculty Publications

In this project we examined the effect of adult age on visual word recognition by using combined reaction time (RT) and accuracy methods based on the Hick–Hyman law. This was necessary because separate Brinley analyses of RT and errors resulted in contradicting results. We report the results of a lexical decision task experiment (with 96 younger adults and 97 older adults). We transformed the error data into entropy and then predicted RT by using entropy values separately for exposure duration (thought to influence peripheral processes) and word frequency (thought to influence central processes). For exposure duration, the entropy–RT functions indicate …

Adaptive Intelligent User Interfaces With Emotion Recognition, Fatma Nasoz

Electronic Theses and Dissertations

The focus of this dissertation is on creating Adaptive Intelligent User Interfaces to facilitate enhanced natural communication during the Human-Computer Interaction by recognizing users' affective states (i.e., emotions experienced by the users) and responding to those emotions by adapting to the current situation via an affective user model created for each user. Controlled experiments were designed and conducted in a laboratory environment and in a Virtual Reality environment to collect physiological data signals from participants experiencing specific emotions. Algorithms (k-Nearest Neighbor [KNN], Discriminant Function Analysis [DFA], Marquardt-Backpropagation [MBP], and Resilient Backpropagation [RBP]) were implemented to analyze the collected data signals …

Speech Enabled E-Learning Technology For Adult Literacy Tutoring, Jason Meade

Theses

This research presents the work involved in developing a speech-enabled e-Learning prototype for use in literacy tutoring. As the main objective was to develop an interface for literacy learning, initial research concentrated on establishing a framework for literacy e-Leaming through the use of speech technology. Requirements for best practice e-Learning and the relevance of learning theories to an e-Learning application were also investigated. The technologies to facilitate this, such as text to speech technologies and mark-up languages, were addressed during the implementation of speech-enabled prototypes. Both server-side and client-side prototypes were implemented to investigate speech technology. Testing found the server-side …

Digital Mountain: From Granite Archive To Global Access, William A. Barrett, Luke A. D. Hutchison, Douglas J. Kennard, Heath E. Nielson, Dallan Quass

Faculty Publications

Large-scale, multi-terabyte digital libraries are becoming feasible due to decreasing costs of storage, CPU, and bandwidth. However, costs associated with preparing content for input into the library remain high due to the amount of human labor required. This paper describes the Digital Microfilm Pipeline – a sequence of image processing operations used to populate a large-scale digital library from a “mountain” of microfilm and reduce the human labor involved. Essential parts of the pipeline include algorithms for document zoning and labeling, consensus-based template creation, reversal of geometric transformations and Just-In-Time Browsing, an interactive technique for progressive access of image content …

A Case For Proof Making For Prospective Middle School Teachers, J. W. Whitenack, L. A. Lovin, L. Cavey

Journal of Mathematics and Science: Collaborative Explorations

In this article, we discuss how we, as mathematics teacher educators, might help our prospective middle school teachers develop a disposition toward mathematics that involves making sound arguments and, more generally, making proofs about mathematical ideas. First, we illustrate what we mean by making sound mathematical proofs. We then use this definition to characterize what ninety-two prospective middle school teachers consider to be proof making, based on a survey that we administered in their first mathematics course. Following our findings, we discuss how we, as teacher educators, might realign our instruction to provide opportunities for prospective teachers to develop new …

A Similarity Based Concordance Approach To Word Sense Disambiguation, Ramakrishnan B. Guru

Masters Theses

This study attempts to solve the problem of Word Sense Disambiguation using a combination of statistical, probabilistic and word matching algorithms. These algorithms consider that words and sentences have some hidden similarities and that the polysemous words in any context should be assigned to a sense after each execution of the algorithm. The algorithm was tested with sufficient sample data and the efficiency of the disambiguation performance has proven to increase significantly after the inclusion of the concordance methodology.

Better Foreground Segmentation Through Graph Cuts, Nicholas Howe, Alexandra Deschamps

Computer Science: Faculty Publications

For many tracking and surveillance applications, background subtraction provides an effective means of segmenting objects moving in front of a static background. Researchers have traditionally used combinations of morphological operations to remove the noise inherent in the background-subtracted result. Such techniques can effectively isolate foreground objects, but tend to lose fidelity around the borders of the segmentation, especially for noisy input. This paper explores the use of a minimum graph cut algorithm to segment the foreground, resulting in qualitatively and quantitiatively cleaner segmentations. Experiments on both artificial and real data show that the graphbased method reduces the error around segmented …

Building Successful On-Line Learning Communities Across International Boundaries: A Case Study, Pat Jefferies, Frances Grodzinsky, Joe Griffin

School of Computer Science & Engineering Faculty Publications

The development of on-line learning communities across international boundaries is now a viable proposition using available asynchronous technologies. As has been reported in previous papers (Grodzinsky, Griffin & Jefferies, 2002; Griffin, Grodzinsky & Jefferies, 2002) such use has proved to be extremely valuable for supporting the teaching of computing and ethics. For example, not only does asynchronous computer conferencing offer new opportunities for students to gain valuable first-hand experience in using such technology to communicate with peers in other countries but it also facilitates them gaining a more direct appreciation of the cultural, legal and ethical differences that abound. However, …
