An l-class classification problem is split into l two-class problems. Crude subnetworks are initially obtained for each of these two-class problems via rough set theory. These subnetworks are then combined and the final network is evolved using a GA with restricted mutation operator which utilizes the knowledge of the modular structure already generated, for faster convergence.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

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 combination of these and cryptography, thereby attempting to achieve a high level of data security. The first phase of our encryption process deals with concepts from molecular genetics involving meiosis, fertilization, translation and mutation. Our next phase involves the encryption of data in the form of images. We have tested the algorithm to encode data and image files. Results are presented in the form of sample images.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

An important aspect of modern thin film design work is the use of computers to match the multilayer parameters to a set of optical specifications such as a desired reflectance curve. There are several basic approaches to the design of thin film multilayer coatings. These include graphical, analytical and digital design methods. The latter, representing both local and global minimum seeking algorithms, are particularly powerful because they lend themselves to the design of coatings with much more complicated properties than is possible with the other methods. Many traditional optimization techniques, including simplex, gradient, and damped least squares method, have been used in this field. However, up to now it has not been possible to say if one of these techniques gives the optimal solution of the problem to be solved. A genetic algorithm is introduced to search for the optimal optical thin film design. The paper discusses the problem of thin film design in greater detail. It shows how a genetic algorithm can evolve the design for better performance. Examples of designs obtained by GA optimization techniques are given.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

The paper discusses, in brief, the theory of fractals and the imaging process. The fractal dimension from image data is calculated using second-order statistics and the Fourier power spectrum. The image fractal model is then used to separate out the homogeneous and inhomogeneous regions. An algorithm is presented to compute the fractal dimension of various blocks; second-order statistics for homogeneous regions and another method for inhomogeneous regions. The algorithm is implemented on synthetic textures as well as on real images.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

Instead of applying single valued input-output information, multivalued information in the form of a K-dimensional vector (K>1) is applied to each node of the input-output layer. Weights are adjusted using the gradient decent approximation method in order to minimise the sum-squared error value at each node of the output layer. The training algorithm has been studied for wide range of input-output values and gives worthy results especially when the output vector is small enough compared to the input vector. The paper suggests a judicious method for choosing the bias component of the sigmoidal activation function used in the training algorithm.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

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 condition for the problem. The stability and convergency of the neural network is investigated and the strategy of the neural optimization is discussed.

The paper presents an O(logn) algorithm, called the \"generalized virtual node (GVN)\" algorithm; the GVN algorithm is a search algorithm for data fragments that have similar contents to that of a query. An example of the use of the GVN algorithm is in the search of a database of audio recordings for a few measures of a melody. Each audio clip is transformed into characteristic features and these features are stored in a hierarchical multidimensional structure, called a \"k-tree\". The k-tree is exploited to build a unified retrieval model for any types of multimedia data. The experimental results of this \"in-clip\" search algorithm on an audio database demonstrate a search quality is qualitatively and quantitatively acceptable, with a retrieval time faster than other algorithms, such as brute-force and partial matching.","PeriodicalId":110736,"journal":{"name":"Proceedings Third International Conference on Computational Intelligence and Multimedia Applications.

It was shown that, an empirical relationship exists between the parameter /spl rho/ of CIPP and estimated local Hurst parameter H. This feature is made use of to study the effect of degree of self-similarity of background network traffic on various performance measures.
