Data Mining: Multimedia, Soft Computing, and BioinformaticsWhile the digital revolution has made huge volumes of high dimensional multimedia data available, it has also challenged users to extract the information they seek from heretofore unthinkably huge datasets. Traditional hard computing data mining techniques have concentrated on flat-file applications. Soft computing tools - such as fuzzy sets, artificial neural networks, genetic algorithms and rough sets - however, offer the opportunity to apply a wide range of data types to a variety of vital functions by handling real-life uncertainty with low-cost solutions. "Data Mining: Multimedia, Soft Computing, and Bioinformatics" provides an accessible introduction to fundamental and advanced data mining technologies. |
