We present a mechanism called the Markov model mediator (MMM) to facilitate the effective retrieval for content-based image retrieval (CBIR). Different from the common methods in content-based image retrieval, our stochastic mechanism not only takes into consideration the low-level image content features, but also learns high-level concepts from a set of training data, such as access frequencies and access patterns of the images. The advantage of our proposed mechanism is that it exploits the structured description of visual contents as well as the relative affinity measurements among the images. Consequently, it provides the capability to bridge the gap between the low-level features and high-level concepts. Our experimental results demonstrate that the MMM mechanism can effectively assist in retrieving more accurate results for user queries. © 2003 IEEE.

An embodied virtual face-to-face communication system is developed for three human interaction supports and the analysis by synthesis. The system provides networked virtual communication environment in which three remote talkers can share embodied interactions by observing their interaction of avatars called VirtualActors including themselves in the same virtual space. The effectiveness of the system is demonstrated by the sensory evaluation of the communication experiment and selected most favorite viewpoint when talker's own VA was semitransparently presented in 8 groups, 3 talkers per group. The importance of mutual embodied sharing in communication is also clarified. The system would be expected to form the foundation of group embodied interaction support system as well as the analysis and understanding of group embodied interaction.

Understanding and learning the subjective aspect of humans in Content-Based Image Retrieval has been an active research field during the past few years. However, how to effectively discover users’ concept patterns when there are multiple visual features existing in the retrieval system still remains a big issue. In this book chapter, we propose a multimedia data mining framework that incorporates Multiple Instance Learning into the user relevance feedback in a seamless way to discover the concept patterns of users, especially where the user’s most interested region and how to map the local feature vector of that region to the high-level concept pattern of users. This underlying mapping can be progressively discovered through the feedback and learning procedure. The role the user plays in the retrieval system is to guide the system mining process to his/her own focus of attention. The retrieval performance is tested to show the feasibility and effectiveness of the proposed multimedia data mining framework. © Springer-Verlag Berlin Heidelberg 2003.

It is very important to provide analysts with guaranteed error bounds for approximate aggregate queries in many current enterprise applications such as the decision support systems. In this paper, we propose a general technique to provide tight error bounds for approximate results to OLAP range-sum queries. We perform an extensive experiment on diverse data sets, and examine the effectiveness of our proposed method with respect to various dimensions of the data cube and query sizes. © Springer-Verlag Berlin Heidelberg 2003.

IEEE International Frequency Control Symposium

The interaction of solid particles with various surfaces has been experiencing growing interest in the area of nanotechnology, colloidal science and biology. In this paper interactions of solid particles with various surfaces using piezoelectric thickness shear mode (TSM) sensors have been studied. A mechanical model has been presented to evaluate the effect of particle loading on the behavior of a TSM sensor. The main sources contributing to the interaction, such as Van der Waals force, gravitational force and electrostatic force, are discussed. Experimental results have shown that the resonant frequency of a TSM sensor depends on the coupling conditions of micro- or nano- particles loaded on the surfaces of a TSM sensor, which is predicted by the theoretical model. The results show that this TSM sensor technique can provide the information of the coupling, such as the binding energy between the particles and the sensor surfaces, and may promote the applications of TSM sensors in characterizing the properties of the loaded particles.

This paper describes the on-line voltage security assessment environment developed within the framework of the EU-sponsored OMASES project, as well as its application to the Greek Interconnected Power system. The heart of all computations is a fast time-domain method. Security is analyzed with respect to power transfers in critical corridors or power consumption in load areas. Results take on the form of either pre-contingency secure operation limits, or post-contingency load-ability limits, together with various diagnosis tips. Typical results obtained during the test phase of the project are reported.

In order to use data information in the Internet, it is necessary to extract data from web pages. An HTT tree model representing HTML pages is presented. Based on the HTT model, a wrapper generation algorithm AGW is proposed. The AGW algorithm utilizes comparing and correcting technique to generate the wrapper with the native characteristic of the HTT tree structure. The AGW algorithm can not only generate the wrapper automatically, but also rebuild the data schema easily and reduce the complexity of the computing.

In this paper, a powerful open Multiple Instance Learning (MIL) framework is proposed. Such an open framework is powerful since different sub-methods can be plugged into the framework to generate different specific Multiple Instance Learning algorithms. In our proposed framework, the Multiple Instance Learning problem is first converted to an unconstrained optimization problem by the Minimum Square Error (MSE) criterion, and then the framework can be constructed with an open form of hypothesis and gradient search method. The proposed Multiple Instance Learning framework is applied to the drug activity problems in bioinformatics applications. Specifically, experiments are conducted on the Musk-I dataset to predict the binding activity of drug molecules. In the experiments, an algorithm with the exponential hypothesis model and the Quasi-Newton method is embedded into our proposed framework. We compare our proposed framework with other existing algorithms and the experimental results show that our proposed framework yields a good accuracy of classification, which demonstrates the feasibility and effectiveness of our framework.

In order to fulfill the functional requirements of multimedia management systems while achieving the efficiency and reliability at the same time, we adopt the component-based design to develop a complicated distributed multimedia management system called DMMManager in this paper. DMMManager integrates a set of core components for managing multimedia data, such as content-based retrieval for image and video data, and multimedia presentation design and rendering. Component-based design makes the reuse and share of the components easy and reliable, and thus avoids the waste of both time and man power in the development cycle. Moreover, new applications can be easily integrated into this system as a new development and utilize the existing components. Besides component reuse, the system is also designed to facilitate information reuse. For example, the output of the image/video retrieval component can be taken as the input for the multimedia presentation component. In addition, the use of subnetworks in our multimedia presentation design also enables the modularized reuse of the existing presentation models that are previously created.
