In many practical applications, there are a great number of unlabeled samples available, while labeling them is a costly and tedious process. Therefore, how to utilize unlabeled samples to assist digging out potential information about the problem is very important. In this paper, we study a multiclass semi-supervised classification task in the context of multiview data. First, an optimization method...
Nowadays, the attacks on the Internet are becoming more complex, advanced and concealed. A large number of security threats arise. The signature-based detection technology is efficient and simple which is widely used for malicious codes detection system. In this paper, we firstly focus on the principle of the method, and summarize the specific steps to implement it, especially feature extraction,...
Knowledge graph is useful for many different domains like search result ranking, recommendation, exploratory search, etc. It integrates structural information of concepts across multiple information sources, and links these concepts together. The extraction of domain specific relation triples (subject, verb phrase, object) is one of the important techniques for domain specific knowledge graph construction...
E-commerce has become a vital contributor to China's national economy. A mass of users' behavioral data on E-commerce platforms such as browse, click and purchase have being accumulated during DT era. Using machine learning algorithms to explore patterns behind big data grows into a new focus of research. In this paper, firstly, we use SQL Server to do feature extraction on those behavioral data....
Medical data often contains a large number of irrelevant and redundant features and a relatively small number of cases, which dramatically impact quality of diseases diagnosis. Hence, in quest for higher differentiation quality, feature selection is expected to improve differentiation performance. In this paper, we describe a heuristic approach based on Rough Sets theory and information theory, for...
Nowadays, the lung lobe segmentation is the most basic step in Lung CAD (Computer-aided diagnosis) and is playing an increasingly important role in the early diagnosis of lung diseases and the analysis of pulmonary functions. The key to achieving lung lobe segmentation is to detect and locate lung fissures. With the wide applications of HRCT (High-Resolution Computed Tomography), CT data with higher...
In this paper, we propose a multimodal query suggestion method for video search engine which can leverage multimodal processing to improve the quality of search results. When users type general or ambiguous textual queries, our system provides keyword suggestions and representative image examples in an easy-to-use dropdown manner which can help users specify their search intent more precisely and...
