Pattern recognition based on learning approaches is regarded as one of the disciplines of AI. Floating search methods, developed originally for feature selection problems in statistical pattern recognition, are applicable to a much wider class of problems outside pattern recognition. They have the potential to find an optimal subset of variables maximizing any criterion adopted for the problem at hand-eliminating the so-called nesting effect from which traditional algorithms suffer. One such application area is multiple regression, where floating search methods represent a computationally feasible alternative to classical methods for finding the optimal set of regressors.

Many artificial and natural systems are often more adequately modelled using data structures, e.g., graphs, trees. For example, it is often more convenient to represent an image using data structures than by representing it using pixels. The data structure can serve as a prelude to scene analysis, image retrieval, etc. There are, broadly speaking, two ways in which data structures can be processed. One way is to consider it as generated by an underlying grammar, with defined syntax; and the other way is to consider it as an input output system, which may be modelled using neural networks. In this talk, we will discuss both approaches. We will first discuss how data structures can be modelled using an attributed grammar. Then, we will discuss the modelling of a data structure using neural networks. It is shown that both approaches are closely related. We will then derive training algorithms for the neural network models, and discuss the universal approximation properties of such models. We will demonstrate the neural network approach on a number of synthesized and practical examples.

Holographic technology has been successfully applied on a number of applications in the fields of pattern recognition and prediction. A short review of the face recognition problem introduces one to the fundamental aspects of holographic technology, which are briefly discussed so that their similarities and differences from typical neural nets are shown. Some of the applications of this tool are mentioned in this paper. The image base used is of 31 images of 10 different faces with different facial expressions (happiness, anger and sadness). Data describing these human faces is explained including the sets of data for supervised training and generalization of the holographic cell. The results of applying this technology to face location, for this data set, show that performance is well above 99% accuracy which supports holographic cells as a sound tool for pattern recognition.

Braille, a touch-reading system for visually impaired people was first introduced in 1825 by Louis Braille. Editing and reprinting Braille text that was originally embossed on paper is both time consuming and labour intensive. This paper presents an automatic system to recognize Braille pages and to convert Braille documents into English or Chinese text for editing.

An important question in the development of system support for distributed multimedia is the type of network service offered to applications. This paper compares two network service disciplines: weighted fair queueing (WFQ) and non-preemptive earliest deadline first (NEDF). We show that, for a broad class of high-bandwidth distributed multimedia applications, WFQ outperforms NEDF in terms of network throughput while still providing an application-adequate end-to-end service. This result holds despite the fact that NEDF offers applications far greater flexibility in terms of control over end-to-end delivery delay.

This paper shows how a multi-agent systems (MAS) approach may be used to build an interactive intelligent tutoring system (ITS) designed as a game. We model the ITS as a society of both reactive and cognitive agents that interact through a graphical interface. We present an experiment carried out in a school in order to test our hypothesis about the architecture's pedagogical potential, and we present the results obtained.

Multimedia applications within the World Wide Web (WWW) have to deal with difficulties like executing within Web pages and being transferred via the Internet. However, the temporal aspects of hypermedia features for continuous media like audio and video resemble all other kinds of multimedia applications. These temporal aspects are discussed in consideration of presentation and authoring facilities. A system architecture and implementation relying on commercial WWW technology is presented.

This paper reports our work in developing the guidance metric to evaluate a hypermedia design for computer-assisted learning (CAL). The metric is based on an integration of two different aspects of an educational hypermedia system. The first aspect is on the structural part which is related to the links between different hypermedia documents in a CAL package. The second aspect is how the organization of different types of educational hypermedia documents affects the performance of a CAL package. An Internet courseware "Interactive Physics Laboratory" (IPL) has been developed to verify the effectiveness of the metric. The results of our preliminary experiments have shown that the metric is suitable and can be useful in developing educational hypermedia systems.

We present a generic architecture for content based retrieval of images, which can be extended to the requirements of large distributed and heterogeneous collections. The system is modeled as a multi agent system where an autonomous search agent encapsulates independent image retrieval algorithms. An optimal team of agents is dynamically selected for every retrieval problem. A flexible protocol allows for dynamic addition of search agents incorporating new pattern recognition techniques. These agents are coded as mobile agents, so that they can travel across a wide area network and analyze the documents at their sources. The separation of physical image forms and their logical structural composition allows the search agents to operate over heterogeneous repositories. A prototype implementation validates the effectiveness of the architecture.

The innovative exploitation of information technologies and communication promises to improve the quality, flexibility and effectiveness of engineering education. The present application, SEACom, is a bilingual system which is divided into two main versions; one Portuguese and the other in English, called TeSa-Teaching System Architecture for the production of printed circuit boards (PCB). The aim is the integration of new technology based media with existing teaching methods and the impact this will have on student learning. The most important phases in the project and manufacturing of electronic components-PCBs-are presented to the student and this has nine stages of production and three levels of interface; basic, intermediate and advanced that represent an ergonomic interface. Meanwhile, you can navigate among this levels and stages in a friendly way via a tele-learning scenario. Several evaluation questionnaires are suggested and one intelligent agent help option is available, in which there is detailed information about a real CIM production line for PCBs with animated images. All of this is developed in a multimedia environment, supported by the World Wide Web (WWW).
