This paper focuses on the Web-based English-Chinese Out-of-Vocabulary (OOV) term translation pattern, and emphasizes particularly on the selection strategy based on the multi-feature representation for translation evaluation. Three kinds of feature, local feature, global feature and Boolean feature, are extracted from translation candidates based on the fusion strategy of multi-features. By utilizing...
Block detector using crystals coupled to circular photomultipliers (PMTs) is commonly used in positron emission tomography (PET). We design a novel PET block detector with cross-shape PMT layout (CSPL). The block detector consists of 9×9 lutetium orthosilicate (LSO) pixelated crystal array (2.2mm×2.2mm×10mm) and five PMTs (four 3/4 inch with circular envelope, one 3/8 inch with square envelope) arranging...
A new text categorization method based on singular value decomposition (SVD) and cascade correlation (CC) algorithm is proposed. Most traditional classification systems represent the contents of documents with vector space model (VSM) which represents documents with a set of index terms. However, this model needs a high dimensional space to represent the documents and it does not take into account...
In order to forecast the corporate finance performance, we must choose the appropriate forecast method. The forecast model widely used at present lacks generalization ability and the accuracy is not approving. In this paper, we propose an improved version of support vector machines (named AdaBoost support vector machine) to forecast financial performance of Chinese listed companies. In the choice...
