    A novel content based video query agent (VQA) for querying distributed video databases using a multimodal (image and sound) index was proposed. As the image search engine, a simple and variable dimension feature based matching method was adopted and an optimum representative frames (r-frames) selection technique was used for the automatic indexing method. Comparative experiments with the conventio... View full abstract»

    The continuing increase in packing density of VLSI circuits requires that the inspection process be completely automated. The paper suggests a new method for automatic inspection of that part of the wire bond where the wire connects to the bond pad on the chip. A popular type of bonding (connected to bond pad) known as “ball bond” is considered. Although several approaches for ball bon... View full abstract»

    We present an intelligent search tool which we developed in order to automate search and evaluation of Web sites. We used TFIDF heuristics to determine term frequency and decision trees to evaluate the quality of sites. Training set for the decision tree contained manually evaluated Web sites. Each Web site was described by the combination of various attributes, complexity metrics and the evaluati... View full abstract»

    We introduce a novel approach to cryptography by amalgamating two cryptic concepts: molecular genetics and image patterning. The genetic code for an organism is unique and yet to be cracked. Formed on the basis of just four nucleotide bases, numerous variations of characteristics are produced. At the same time, encoding using images gives rise to millions of patterns. We draw a parallel between a ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (132 KB)

    Autonomous state generalization is one of the key issues in the behavior acquisition problem of reactive agents. The paper proposes a novel state generalization method which discretizes the continuous sensor space based on entropy minimization of agents' behavior outcomes. This general framework unifies the heuristic criteria for state generalization used in conventional works. An experimental stu... View full abstract»

    According to the basic optimization principle of artificial neural networks, a novel kind of neural network model for solving the quadratic programming problem is presented. The methodology is based on the Lagrange multiplier theory in optimization and seeks to provide solutions satisfying the necessary conditions of optimality. The equilibrium point of the network satisfies the Kuhn-Tucker condit... View full abstract»

    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 ... View full abstract»

    Publication Year: 1999, Page(s):65 - 69
    Request permission for commercial reuse | Click to expandAbstract |PDF file iconPDF (32 KB)

    The paper presents the formulation of a VLSI placement problem for regular designs (gate arrays) using a Kohonen self-organizing map. An abstract specification of the design is converted to a set of appropriate input vectors using a mathematical method, called “multidimensional scaling”. These vectors which have, in general, higher dimensionality, are fed to the self-organizing map at ... View full abstract»

    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 pre... View full abstract»

    In this paper, we model the background network traffic by CIPP in an ATM multiplexer while simulating the end-to-end transport of real world VBR traffic over ATM networks. CIPP has been proposed by Manivasakan et al. (1999) for modeling broadband teletraffic. It was shown that, an empirical relationship exists between the parameter ρ of CIPP and estimated local Hurst parameter H. This feature ... View full abstract»

    We believe that parallelism is strongly connected with artificial neural networks (ANN), as biological neural networks are known to make good use of massive parallelism. At present, there has been little research in this direction. We have designed and implemented parallel ANNs on different environments. The best implementation possibilities are given, naturally, by massively parallel computers (d... View full abstract»
