International IEEE Conference on Intelligent Systems, IS

Global optimization algorithm applied for feedforward neural networks (NN) supervised learning is investigated. The network weights are determined by minimizing the traditional backpropagation error function. The difference is that the optimization based learning algorithm utilizes stochastic technique, based on the use of low discrepancy sequences. This technique searches the parameter space, defined by the network weights, to define initial regions of attraction with candidates for local minima, and then exploits each region to locate the minima, and to determine a global minimum. The proposed technique is initially tested on multimodal mathematical functions and subsequently applied for training NN with moderate size for solving simple benchmark problems. Finally, the results are analysed, discussed, and compared with others.

The current debate about the teaching of data structures is hampered because, as a community, we usually debate specifics about data structure implementations and libraries, when the real level of disagreement remains implicit - the intent behind our teaching. This paper presents a phenomenographic study of the intent of CS educators for teaching data structures in CS2. Based on interviews with computer Science educators and analysis of CS literature, we identified five categories of intent: developing transferable thinking, improving students' programming skills, knowing "what's under the hood", knowledge of software libraries, and component thinking. The CS community needs to first debate at the level of these categories before moving to more specific issues. This study also serves as an example of how phenomenographic analysis can be used to inform debate on syllabus design in general. Copyright 2004 ACM.

In this paper, the personified home service system is described through making use of heuristic genetic algorithm and extending the human interaction with resource description framework (RDF) schema. The human-computer interaction (HCI) interface is distributed and ubiquitous. Sensor, TV, refrigerator etc. could be used as interactive device not only Mouse and CRT. RDF schema describe them to control TV, refrigerator, air-condition and so on. For extensive intelligence in the system, the system analyzed a daily record, predicted the user's interest, and provided the heuristic genetic algorithms to implement a natural, kindly and vivid home service system.

The error-backpropagation (EBP) algorithm for learning multilayer perceptrons (MLPs) is known to have good features of robustness and economical efficiency. However, the algorithm has difficulty in selecting an optimal constant learning rate and thus results in non-optimal learning speed and inflexible operation for working data. This paper introduces an elastic learning rate that guarantees convergence of learning and its local realization by online update of MLP parameters into the original EBP algorithm in order to complement the non-optimality. The results of experiments on a speaker verification system with Korean speech database are presented and discussed to demonstrate the performance improvement of the proposed method in terms of learning speed and flexibility for working data of the original EBP algorithm. © Springer-Verlag Berlin Heidelberg 2004.

Test-first development is a practice of extreme programming designed to produce reliable software quickly. Rather than writing the code first, a software engineer first creates the tests that will demonstrate that the software works correctly. Coding follows and is often guided by the tests. Practitioners of this method claim that the discipline of developing the tests before the code focuses their attention on the right problems and yields cleaner code. Test-first teaching is a method of course development that incorporates instructional design methods to create more effective instruction. The instruments that will be used to test students' day-to-day learning of the course material-assignments and quizzes-are created first, and instruction is developed to meet the students' needs. Components of test-first teaching are applied at both course and lecture levels. Test-first teaching has been used successfully to develop courses for the new Bachelor of Science in software engineering program at Rose-Hulman institute of technology.

SWENET, the network community for software engineering education, is an NSF funded project to develop curriculum modules of value to faculty members desiring to incorporate software engineering concepts in new or existing courses. By design, the modules are self-contained instructional units ranging from a single lecture to approximately one week of course material. In this way, instructors can adopt, adapt, and arrange modules as appropriate to their courses. This presentation will provide an update on the status of the project including a report of current progress and problems encountered. The session will also address the future of the course materials collection and solicit input on ways to provide ongoing support to the community of software engineering researchers.

Web application testing is concerned with numerous and complicated testing objects, methods and processes. So a testing framework fitting for the properties of Web application is needed to guide and organize all the testing tasks. Based on the analysis for Web application characters and traditional software testing process, the process for Web application testing is modeled, which describes a series of testing flows such as the testing requirement analysis, test cases generation and selection, testing execution, and testing results analysis and measurement. Furthermore, the realization techniques are also investigated so as to integrate each testing step and implement the whole testing process harmoniously and effectively. Thus the framework is suitable for the Internet environment and can guide the Web application testing actively and availably.

Speaker verification systems based on multilayer perceptrons (MLPs) have good prospects in reliability and flexibility as required for a successful authentication system. However, poor learning speed of error backpropagation (EBP), the representative method of learning for MLPs, has been the major problem which must be resolved to achieve real-time user enrollment. In this paper, we implement an MLP-based speaker verification system by applying methods of omitting patterns in instant learning (OIL) and discriminative cohort speakers (DCS) to approach the real-time enrollment. We evaluate the system on a Korean speech database and demonstrate the feasibility of it as a speaker verification system of high performance. © Springer-Verlag Berlin Heidelberg 2004.

This paper proposes a unified knowledge model establishing a core structure of knowledge representation in natural and artificial intelligence systems. The Concept Cell Model proposes the use of acyclic lattices to model a concept formed from a knowledge network of simpler concepts. Declarative and procedural knowledge are explicitly defined as the time-invariant and time-variant relationship of concepts. Examples of a Restaurant Servicing Concept Cell and an extended Shopping Complex Concept Cell are used to demonstrate the functionality of this model. Major existing theoretic and engineering Ontology knowledge schools are compared under this framework.

The SDL Forum Society holds workshops on the languages SDL (Specification and Description Language) and MSC (Message Sequence Charts). At the 2002 workshop (SAM2002), held at Aberystwyth, Wales, an SDL design contest was held to promote discussion about the use of SDL. The contest challenge was to use SDL and MSC to specify a railway crossing system. Our team from the University of Ottawa, consisting of Qing Li, Alan Williams, Robert Probert and Tae-Hyong Kim won the contest. In this paper, we outline our design approach including requirements analysis, high-level design, iterative design construction, design verification, design validation against high-yield scenarios, and design maintenance based on new and changed requirements which arrived close to the end of the design cycle. We also describe the rationale for some of the decisions we had to make during the process. Based on our experience, we provide some comments on the strengths and weaknesses of the methods and tools that we used. © Springer-Verlag Berlin Heidelberg 2003.
