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.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

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.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

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.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

Several decomposition techniques have been developed, and they show better area and level optimization. In a multi-level decomposition method, the coding of the decomposed function is an important factor that influences further decomposition at lower levels. It is particularly important for real-life functions that have a lot of \"don't cares\". In this paper, we propose a coding strategy that retains as many \"don't cares\" as possible. The resulting truth table is smaller in size.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

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.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

We propose a multi-agent architecture to integrate and cooperate object recognition modules for individual target objects. In our system, object candidates generated by different agents are integrated not only on the evaluations by each modules themselves but also on spatial relations among objects. By checking spatial relation, the agents also estimate actual objects from parts seen in the image. Such mechanisms are realized by autonomous cooperation among the agents, and the most reliable result is selected after the arbitration between them.
