Classification of Streaming Fuzzy DEA Using Self-Organizing Map
The classification of fuzzy data is considered as the most challenging areas of data analysis and the complexity of the procedures has been obstacle to the development of new methods for fuzzy data analysis. However, there are significant advances in modeling systems in which fuzzy data are available in the field of mathematical programming. In order to exploit the results of the researches on ...

متن کاملMultidimensional urban sprawl in Europe: A self-organizing map approach
The paper considers urban sprawl in Europe from a multidimensional and exploratory point of view. Several studies on the topic (mainly from urban economics, but also from other fields, such as urban planning or regional science) are reviewed in order to identify the key dimensions of the urban sprawl phenomenon in Europe. These comprise the following six elements: connectivity, decentralization...
متن کاملEstimation of Missing Daily Precipitation and Runoff Using Self-Organizing Map (A Case Study: Mazandaran Province)
Expert aquatic designers face many problems; among these, in hydrology, defective occurrences in time-series can cause errors in the ultimate results of the study. This more often happens in the regions where the number of hydrometric and rain gauge stations is limited. In addition, assessing, developing and maintaining the use of water resources require accessible long-term and high-quality qu...
متن کاملSelf-Organizing Map Convergence
Self-organizing maps are artificial neural networks designed for unsupervised machine learning. They represent powerful data analysis tools applied in many different areas including areas such as biomedicine, bioinformatics, proteomics, and astrophysics. We maintain a data analysis package in R based on self-organizing maps. The package supports efficient, statistical measures that enable the u...
