This paper is for text categorization of Enron email corpus, we use the information bottleneck (IB) method to cluster the key words based on their distribution on different class labels, then we use threads and address groups as additional features to email texts, and the maximal entropy model to improve the accuracy of the classifier. Our experimental results shows that these measures can improve...
The National Geological Parks is a natural zone, featuring a set of unique natural and cultural landscapes, with geological heritages as main body, which is combine aesthetic value with national significance. This paper discusses the architecture, main functions, and Realizing method of the National Geological Parks Park Panorama Display System (NGPDS) based on web2.0, aiming at performing the full...
The rise of frame theory in applied mathematics is due to the flexibility and redundancy of frames. In this work, the notion of a generalized multiresolution structure of L2(R) is proposed. The definition of multiple pseudoframes for subspaces of L2(R) is given. The construction of a generalized multiresolution structure of Paley-Wiener subspaces of L2(R) is investigated. The sufficient condition...
