The Space Of Jumping Emerging Patterns And Its Incremental Maintenance, Jinyan Li, Kotagiri Ramamohanarao, Guozhu Dong

Kno.e.sis Publications

The concept of jumping emerging patterns (JEPs) has been proposed to describe those discriminating features which only occur in the positive training instances but do not occur in the negative class at all; JEPs have been used to construct classifiers which generally provide better accuracy than the state-of-the-art classifiers such as C4.5. The algorithms for maintaining the space of jumping emerging patterns (JEP space) are presented in this paper. We prove that JEP spaces satisfy the property of convexity. Therefore JEP spaces can be concisely represented by two bounds: consisting respectively of the most general elements and the most specific …

Detecting And Representing Relevant Web Deltas Using Web Join, Sanjay Kumar Madria, Wee Keong, Ee-Peng Lim, Sourav S. Bhowmick

Computer Science Faculty Research & Creative Works

We show how to detect and represent Web deltas, i.e., changes in Web information, that are relevant to a user's query in the context of our Web warehousing system called WHOWEDA (Warehouse of Web Data). In WHOWEDA, Web information are materialized views stored in Web tables and can be manipulated and analyzed using a set of Web algebraic operators. We present a mechanism to detect relevant Web deltas using Web join and outer Web join. We show how to represent these changes using delta Web tables.

Reducing Cognitive Overheads In A Web Warehouse Using Reverse-Osmosis, Sanjay Kumar Madria, Wee Keong Ng, Ee-Peng Lim, Sourav S. Bhowmick

Computer Science Faculty Research & Creative Works

This paper provides a quantitative analysis of reducing cognitive overheads in a Web warehouse using an important class of operation called reverse osmosis. The analysis is used to examine two different cognitive overheads of locating relevant nodes or information and display time of a Web table. A reverse-osmosis operation enables us to eliminate in relevant information from a collection of Web documents stored in the form of a Web table. We call such an operation reverse-osmosis because it is analogous to the reverse osmosis process in the field of water purification. We discuss a formal algorithm of the reverse-osmosis operation

A Systolic Image Difference Algorithm For Rle-Compressed Images, Fikret Erçal, Mark Allen, Hao Feng

Computer Science Faculty Research & Creative Works

A new systolic algorithm which computes image differences in run-length encoded (RLE) format is described. The binary image difference operation is commonly used in many image processing applications including automated inspection systems, character recognition, fingerprint analysis, and motion detection. The efficiency of these operations can be improved significantly with the availability of a fast systolic system that computes the image difference as described in this paper. It is shown that for images with a high similarity measure, the time complexity of the systolic algorithm is small and, in some cases, constant with respect to the image size. A formal proof …

Computer Science Faculty Research & Creative Works

The authors discuss association rules which can be discovered from Web data. The association rules are discussed within the scope of our WHOWEDA (warehouse of Web data) project. WHOWEDA is supported by a Web data model and a set of algebraic operators. The Web data model allows a uniform and integrated view of Web data gathered using a user''s query graph. A user''s query graph describes the query by example (what the user perceives as the query) and the Web coupling query gathers instances of such a query graph from the Web and stores them in the form of subgraphs …

Assurance Services For Business-To- Business Electronic Commerce: A Framework And Implications, Deepak Khazanchi, Steve G. Sutton

Information Systems and Quantitative Analysis Faculty Publications

The electronic commerce assurance market has been estimated to be potentially worth $11 billion. To date the focus of assurance services has largely been on web commerce (and therefore business to consumer) related services, leaving the business-to-business (B2B or B-to-B) electronic commerce market relatively untapped. Yet, with Electronic Data Interchange (EDI) being mandated by large companies and government agencies, small- to medium-sized firms have struggled to acquire and implement this technology with little understanding of this new age of electronic commerce. As the ubiquitous Internet allows more firms to become EDI-capable, there is an imminent need for having some independent …

Applying Machine Learning Algorithms To Othello, Kristopher Glesener

Honors Theses, 1963-2015

The goal of this project was to apply unsupervised machine learning algorithms to the board game othello. We used eight genetic algorithms to develop eight different othello strategies. Each genetic algorithm played 2.5 million games to develop one of the eight strategies. Each strategy was then tested against the other seven strategies, as well as other computer players and human players. The results show that most of the strategies play at the level of a beginning player, with the best strategies on par with a slightly experienced player. We also implemented a reinforcement learning algorithm in order to improve on …

Bottom-Up Design Of Artificial Neural Network For Single-Lead Electrocardiogram Beat And Rhythm Classification, Srikanth Thiagarajan

Doctoral Dissertations

Performance improvement in computerized Electrocardiogram (ECG) classification is vital to improve reliability in this life-saving technology. The non-linearly overlapping nature of the ECG classification task prevents the statistical and the syntactic procedures from reaching the maximum performance. A new approach, a neural network-based classification scheme, has been implemented in clinical ECG problems with much success. The focus, however, has been on narrow clinical problem domains and the implementations lacked engineering precision. An optimal utilization of frequency information was missing. This dissertation attempts to improve the accuracy of neural network-based single-lead (lead-II) ECG beat and rhythm classification. A bottom-up approach defined …

A Pairwise Key Pre-Distribution Scheme For Wireless Sensor Networks, Wenliang Kevin Du, Jing Deng, Yunghsiang S. Han, Pramod K. Varshney

Electrical Engineering and Computer Science - All Scholarship

This paper, we provide a framework in which to study the security of key pre-distribution schemes, propose a new key pre-distribution scheme which substantially improves the resilience of the network compared to previous schemes, and give an in-depth analysis of our scheme in terms of network resilience and associated overhead. Our scheme exhibits a nice threshold property: when the number of compromised nodes is less than the threshold, the probability that communications between any additional nodes are compromised is close to zero. This desirable property lowers the initial payoff of smaller-scale network breaches to an adversary, and makes it necessary …

Prioritizing Test Cases For Regression Testing, Sebastian Elbaum, Alexey G. Malishevsky, Gregg Rothermel

School of Computing: Technical Reports

Test case prioritization techniques schedule test cases in an order that increases their effectiveness in meeting some performance goal. One performance goal, rate of fault detection, is a measure of how quickly faults are detected within the testing process; an improved rate of fault detection can pro- vide faster feedback on the system under test, and let soft- ware engineers begin locating and correcting faults earlier than might otherwise be possible. In previous work, we re- ported the results of studies that showed that prioritization techniques can significantly improve rate of fault detection. Those studies, however, raised several additional questions: …

Using Artificial Queries To Evaluate Image Retrieval, Nicholas Howe

Computer Science: Faculty Publications

This paper addresses the evaluation and comparison of algorithms for generalized image retrieval. The forms of evaluation currently in vogue are not calibrated with each other and thus do not allow the comparison of results reported by different research groups. We address the problem by proposing a class of tests that are algorithmically defined and relatively independent of the image test set. The proposed tests can be tailored to investigate retrieval performance under specific sets of adverse conditions, allowing additional insight into the strengths and weaknesses of different retrieval mechanisms.

Design, Implementation, And Evaluation Of Virtual Interface Architecture For Power Pc Machines, Ben Mckenzie

Inquiry: The University of Arkansas Undergraduate Research Journal

The Virtual Interface Architecture (VIA) standard is a low-latency protocol that was designed for use in high-performance networks. VIA improves performance by reducing overhead in messaging. This research has two components. The first part of this research project is the development of a new tool for measuring the performance of a VIA implementation and comparing it to the more traditional high-overhead protocols used on the Internet. The development of the tool represents a significant contribution in and of itself, since the tool has been put into the public domain and will likely become useful by Lima users, both for measuring …

Life And Evolution In Computers, Melanie Mitchell

Computer Science Faculty Publications and Presentations

This paper argues for the possibility of 'artificial life' and computational evolution, first by discussing (via a highly simplified version) John von Neumann's self-reproducing automaton and then by presenting some recent work focusing on computational evolution, in which 'cellular automata', a form of parallel and decentralized computing system, are evolved via 'genetic algorithms'. It is argued that such in silico experiments can help to make sense of the question of whether we can eventually build computers that are intelligent and alive.
