Clustering is recognized as an effective topology maintenance framework to provide better scalability for Wireless Sensor Networks. When loop structures are deployed to topology maintenance, it can provide better robustness and convenient route recovery, for the topology information is disseminated within a loop instead of a single node and the nature of the loop that there are two paths between each pair of nodes within a loop provides backup routes. In this paper, we propose a novel topology maintenance approach based on loop structures. The algorithm is a distributed, on-demand and configurable. It prefers a low-mobility network which is typically suitable for wireless sensor networks. © Springer-Verlag Berlin Heidelberg 2005.

To perform new science and exploration, NASA is proposing missions using multi-spacecraft where each spacecraft can act independently to perform a part of a mission but cannot complete it by itself. These missions are utilizing the concept of "System of Systems" that are being used to develop large systems made up of interacting components, each of which is a system in its own right. To develop these systems with a high level of assurance, new verification methods will be needed to address the added complexity resulting from the nondeterminate nature of these systems as well as emergent behavior. To support the level of assurance that NASA missions require, formal specification techniques and formal verification will play vital roles in the future development of NASA space exploration missions. The role of formal methods will be in the specification and analysis of forthcoming missions, enabling software assurance and proof of correctness of the system of systems behavior, whether or not this behavior is emergent. Formal models derived may also be used as the basis for automating the generation of much of the code for the mission to further reduce the cost and probability of adding new errors during coding.

In this paper, inspired by a unified probabilistic model of information retrieval, we propose a general framework of targeted marketing by considering three types of information, namely, the customer profiles, the product profiles, and the transaction databases. The notion of market value functions is introduced, which measure the potential value or profit of marketing a product to a customer. Four sub-models are examined for the estimation of a market value function. Based on market value functions, two targeted marketing strategies, namely, customer-oriented targeted marketing and product-oriented targeted marketing, are suggested. This paper focuses on the conceptual development of the framework. The detailed computation of a market value function and the evaluation of the proposed framework will be reported in another paper. © Springer-Verlag Berlin Heidelberg 2005.

Investigating manifold learning algorithms based on magnification factors and principal spread directions

As a new unsupervised learning technique, manifold learning has captured the attention of many researchers in the field of machine learning and cognitive sciences. The major algorithms include Isometric mapping (ISOMAP) and Locally Linear Embedding (LLE). The approaches can be used for discovering the intrinsic dimensions of nonlinear high-dimensional data effectively and aim researchers to analyze the data better. How to quantitatively analyze the relationship between the intrinsic dimensions and the observation space, however, has fewer reports. And thus further works in manifold learning may have suffered some difficulties. The paper focuses on two kinds of manifold learning algorithms (ISOMAP, LLE), and discusses magnification factors and principal spread directions from the observation space to the intrinsic low-dimensional space. Also the corresponding algorithm is proposed. Experiments show the effectiveness and advantages of the research.

How to reduce the system' s communication cost is a hard problem because of its strong reliability on the differences incurring by the variant kinds of mobile agents in their execution environments most of which are influenced by synthetical reasons. Making the application components movable inter-system platforms can partly resolve this problem. A new MA system model is given, which divides movable components from fixed components to reduce the communication cost. Resource allocating strategy applied on it is an expanding version of the Avrampopoulos algorithm by adding the parameter to improve its robustness. Experimental results proved its usability and effectiveness.

In recent years, more and more people studied the Bayesian networks learning algorithm that integrates independence test with scoring metric. Based on the proposed hybrid algorithm I-B&B-MDL, a modified method is developed. There are two major contributions. Firstly, order-0 and partial order-1 independence tests are used to obtain an original graph of the network, which reduces the number of independence tests and database passes while effectively restricting the search space. Secondly, by means of the heuristic knowledge of mutual information, sort order for candidate parent nodes increases the cut-offs of the B&B search tree and accelerates search process. The experimental results show that the modified algorithm has high accuracy, and is more efficient in time complexity than other algorithms.

Framework of the distributed β-PSML and its applications

Beijing Gongye Daxue Xuebao / Journal of Beijing University of Technology 2005年第4期31卷 427-433页

作者： Su, Yi-La Liu, Chun-Nian Beijing Municipal Key Laboratory of Multimedia and Intelligent Software Technology College of Computer Science Beijing University of Technology Beijing 100022 China College of Information Engineering Inner Mongolia University of Technology Huhehaote 010062 China

For solving problems in a large-scale distributed Web environment, we propose the distributed β-PSML (problem solver markup language). The distributed β-PSML is an extension of the β-PSML that we have proposed before for complex adaptive, distributed problem solving, and can be easily used for automatic reasoning on the Web. By incorporating global information sources from the Semantic Web and social networks with locally operational knowledge-data bases in an enterprise portal together for decision-making and e-business intelligence, the reason of a distributed β-PSML can be implemented. The experimental results show that our considerations are valid by combining global and local information sources and our preliminary solution works well on the semantic Web.

3rd International Conference on Diagrammatic Representation and Inference, Diagrams 2004

We conducted an eye-tracking study of mechanical problem solving from cross-sectional diagrams of devices. Response time, accuracy and eye movement data were collected and analyzed for 72 problem-solving episodes (9 subjects solving 8 problems each). Results indicate that longer response times and visually attending to more components of a device do not necessarily lead to increased accuracy. However, more focus shifts, visually attending to components in the order of causal propagation, and longer durations of visual attention allocated to critical components of the devices appear to be characteristics that separate successful problem solvers from unsuccessful ones. These findings throw light on effective diagrammatic reasoning strategies, provide empirical support to a cognitive model of comprehension, and suggest ideas for the design of information displays that support causal reasoning. © 2004, Springer-Verlag Berlin Heidelberg, All rights Reserved.

Peculiarity rules are a new type of interesting rules which can be discovered by searching the relevance among peculiar data. A main task of mining peculiarity rules is the identification of peculiarity. Traditional methods of finding peculiar data are attribute-based approaches. This paper extends peculiarity oriented mining to relational peculiarity oriented mining. Peculiar data are identified on record level, and peculiar rules are mined and explained in a relational mining framework. The results from preliminary experiments show that relational peculiarity oriented mining is very effective. © 2004 IEEE.
