The Self-Organizing Map (SOM) is a powerful neural network method for analysis and visualization of high-dimensional data. It maps nonlinear statistical dependencies between high-dimensional measurement data into simple geometric relationships on a usually two-dimensional grid. The mapping roughly preserves the most important topological and metric relationships of the original data elements an...

The standardization of processes and the identification of shared business services in a service-oriented architecture (SOA) are currently widely discussed. Above all in practice, however, there still is a lack of appropriate instruments to support these tasks. In this paper an approach for a process map is introduced which allows for a systematic presentation – as complete as possible – of the...

How can we encourage the application of novel genomic biomarkers in drug development? A major step in this direction would be a consensus on how to interpret results from measurements of these biomarkers in regulatory submissions. A transparent process for genomic biomarker validation would be of value both for the pharmaceutical industry as well as for regulatory agencies associated with it. A...

The Network Map application leverages an existing corporate data repository to provide a synoptic view of the telecommunications services provided by U S WEST to a large business client. The phased architecture uses a server to generate data portfolios (consisting of HTML and hyperbolic tree data files) on a weekly basis; at the end user’s convenience, the portfolios are downloaded on to their ...

in this study, a hybrid algorithm is presented to tackle multi-variables robust design problem. the proposed algorithm comprises neural networks (nns) and co-evolution genetic algorithm (cga) in which neural networks are as a function approximation tool used to estimate a map between process variables. furthermore, in order to make a robust optimization of response variables, co-evolution algor...

Computer interaction, animation and multimedia have changed cartography to a tremendous extent. This phenomenon requires new developments in cartographic theory and methodology. Especially interaction has influenced cartographic information processing decisively. Map-making and map-using have become one single and integrated process. The user is able to process and visualise data according to h...

The paper presents methodology for the incremental map formation in a multi-stage process of a search engine with the map based user interface. The architecture of the experimental system allows for comparative evaluation of different constituent technologies for various stages of the process. The quality of the map generation process has been investigated based on a number of clustering and cl...

We study the departure process of a single server queue with Markovian arrival input and Markov renewal service time. We derive the joint transform of departure time and the number of departures and, based on this transform, we establish several expressions for burstiness (variance) and correlation (covariance sequence) of the departure process. These expressions reveal that burstiness and corr...
