A Multi-Scale Approach For Recognizing Complex Annotations In Engineering Documents., Andrew Francis Laine, William Ball, Arun Kumar
A Multi-Scale Approach For Recognizing Complex Annotations In Engineering Documents., Andrew Francis Laine, William Ball, Arun Kumar
All Computer Science and Engineering Research
This paper describes a novel method of character recognition targeted for extracting complex annotations found in engineering documents. The results of this work will make it possible to capture the information contained in documents used to support facilities management and manufacturing. The recognition problem is made difficult in part because characters and text may be expressed in arbitrary fonts and orientations. Our approach includes a novel incremental strategy based on the multi-scale representation of wavelet decompositions. Our approach is motivated by biological mechanisms of the human visual systems. Using wavelets as a set of basis functions, we may decompose an …
Segment Streaming For Efficient Pipelined Televisualization, Fengmin Gong
Segment Streaming For Efficient Pipelined Televisualization, Fengmin Gong
All Computer Science and Engineering Research
The importance of scientific visualization for both science and engineering endeavors has been well recognized. Televisualization becomes necessary because of the physical distribution of data, computation resources, and users involved in the visualization process. However, televisualization poses a number of challenges to the designers of communication protocols. A pipelined televisualization (PTV) model is proposed for efficient implementation of a class of visualization applications. Central to the proposed research is the development of a segment of streaming IPC (interprocess communication) mechanism in support of efficient pipelining across very high speed internetworks. This requires exploration of special issues arising from extending a …

Highly Concurrent Logically Synchronous Multicast, Kenneth J. Goldman
Highly Concurrent Logically Synchronous Multicast, Kenneth J. Goldman
All Computer Science and Engineering Research
We define the logically synchronous multicast problem, which imposes a natural and useful structure on message delivery order in an asynchronous system. In this problem, a computation proceeds by a sequence of multicasts, in which a process sends a message to some arbitrary subset of the processes, including itself. A logically synchronously multicast protocol must make it appear to every process as if each multicast occurs simultaneously at all participants of that multicast (sender plus receivers). Furthermore, if a process continually wishes to sends a message, it must eventually be permitted to do so. We present a highly concurrent solution …

Studies In The Hybrid Deterministic Parsing, Stan C. Kwasny, Anne M. Johnstone, Barry L. Kalman
Studies In The Hybrid Deterministic Parsing, Stan C. Kwasny, Anne M. Johnstone, Barry L. Kalman
All Computer Science and Engineering Research
This report details research plans to extend work on hybrid deterministic parsing. The approach is hybrid in its combination of symbolic and sub-symbolic (connectionist) approaches. The research is investigating (1) new and more robust architectures for deterministic parsing which are hybrid mixtures of symbolic and sub-symbolic components, (2) combinations of syntax with lexical access and other components of natural language processing in order to determine how the distributed patterns of connectionism may enable better interfaces among these components, and (3) properties of the rules in the rule-based deterministic processing of natural language that make them most suitable for sub-symbolic training. …

Super Linear Learning In Back Propagation Neural Nets, Barry L. Kalman
Super Linear Learning In Back Propagation Neural Nets, Barry L. Kalman
All Computer Science and Engineering Research
The important feature of this work is the combination of minimizing a function with desirable properties, using the conjugate gradient method (cgm). The method has resulted in significant improvements for both easy and difficult training tasks. Two major problems slow the rate at which large back propagation neural networks (bpnns) can be taught. First is the linear convergence of gradient descent used by modified steepest descent method (msdm). Second is the abundance of saddle points which occur because of the minimization of the sum of squared errors. This work offers a solution to both difficulties. The cgm which is super …

The Equivalence Of Connectionist Energy Minimization And Propositional Calculus Satisfiability, Gadi Pinkas
The Equivalence Of Connectionist Energy Minimization And Propositional Calculus Satisfiability, Gadi Pinkas
All Computer Science and Engineering Research
Quadratic energy minimization is the essence of certain connectionist models. We define high order connectionist models to support the minimization of high order energy functions and we prove that high order energy functions are equivalent to quadratic ones. We show that the standard quadratic models can minimize high order functions using additional hidden units and we demonstrate trade-offs of size (number of hidden units), order of the model, and fan-out. We prove an equivalence between the problem of satisfiability in propositional calculus and the problem of minimization of energy functions. An energy function describes a Well Formed Formula (WFF) if …
The Fat-Pyramid: A Robust Network For Parallel Computation, Ronald I. Greenberg
The Fat-Pyramid: A Robust Network For Parallel Computation, Ronald I. Greenberg
Computer Science: Faculty Publications and Other Works
This paper shows that a fat-pyramid of area Theta(A) built from processors of size lg A requires only O(lg^2 A) slowdown in bit-times to simulate any network of area A under very general conditions. Specifically, there is no restriction on processor size (amount of attached memory) or number of processors in the competing network, nor is the assumption of unit wire delay required. This paper also derives upper bounds on the slowdown required by a fat-pyramid to simulate a network of larger area in the case of unit wire delay.
Data Communication Between An Expert System Shell And A Conventional Algorithmic Program With Application To Cam Motion Specification, Paul P. Lin, An-Jen Yang
Data Communication Between An Expert System Shell And A Conventional Algorithmic Program With Application To Cam Motion Specification, Paul P. Lin, An-Jen Yang
Mechanical Engineering Faculty Publications
Although more and more expert system shells have begun to provide communication interfaces to conventional procedural languages, the interfaces are basically shell- and language-dependent. This paper presents a simple, shell- and language-independent data communication technique between a shell and a procedural language via a concept analogous to the handshake data transmission used in microprocessors. A control file is used for the action of handshake. The communication interface is between two data files in two different language environments. A program written in a LISP-based expert system shell, OPS 5, and one written in a procedural language, FORTRAN, were …

All Computer Science and Engineering Research
This project provides a good case study of expert system development with untrained experts over a short period of time. We describe the development of a working medical screening and diagnosis expert system for use at the Women, Infants and Children (WIC) clinics in Madison County, Illinois. The system was designed and implemented over the period of four months. A large number of knowledge acquisition techniques were employed, some of them customized in ways that greatly increased their effectiveness. This paper explores the development of THE WIC Advisor, from problem definition through expert system delivery. The knowledge acquisition methods used …

Application Of Case-Based Reasoning Techniques To The Automation Of Single-Family Residential Property Appraisals, Raymond Laureano-Ortiz
Application Of Case-Based Reasoning Techniques To The Automation Of Single-Family Residential Property Appraisals, Raymond Laureano-Ortiz
Retrospective Theses and Dissertations
Case-based reasoning has emerged as an alternative to rule-based reasoning techniques for the design of expert systems. This paper concentrates on the issues involved in the application of the case-based reasoning techniques to a specific domain, property appraisal. Case-based reasoning has been recently favored because it seems to resemble more closely to the psychological process human follows when trying to apply their knowledge to the solution of problems: People adapt solutions of similar problems they handled in past experiences to address present situations.
Property appraisal or valuation is a domain characterized by having a single parameter in its solution, that …

Metamodeling Aspects Of Model Conceptualization, Wayne W. Wakeland
Metamodeling Aspects Of Model Conceptualization, Wayne W. Wakeland
Systems Science Faculty Publications and Presentations
This paper suggests a technique for improving the conceptualization of models. The key aspect of this technique is to set aside the main model for a period of time during the model conceptualization process and focus on building a "watchdog" submodel. The primary purpose of the watchdog submodel is to assure that the main model remains internally consistent during its operation. In the experience of this author, such a submodel can help to identify model conceptualization errors and to determine if a model is sufficiently "robust" to adequately replicate the behavior of the system being modeled.
This is not a …
Counterpropagation Neural Network Detection Of Visual Primitives, Cynthia Lynn Johnson
Counterpropagation Neural Network Detection Of Visual Primitives, Cynthia Lynn Johnson
Retrospective Theses and Dissertations
Psychological testing has shown that there is an early preattentive stage in the human visual system. At this level, simple features and properties of objects known as visual primitives are detected spatially in parallel by groupings of cells in the visual cortex known as feature maps. In order to study this preattentive stage in a machine vision system, the biologically inspired, highly parallel architecture of the artificial neural network shows great promise. This paper describes how the unique architecture of the counterpropagation neural network was used to simulate the feature maps which detect visual primitives in the human visual system. …
