The user often retrieves few anticipated results when searching information in Internet via generalized search engine due that the web pages also exist the synonymous and ambiguous characteristic. How to classify the webpage is the key point to construct vertical search engine, which is known as solution for the problems. This paper proposes a conceptual framework based on Learning Vector Quantization (LVQ) network and Ontology to automatic classification for the webpage from agricultural website. System test shows that the framework can automatically classify Chinese agricultural products web pages and perfectly resolve the synonymous problem.

A fuzzy clustering algorithm for intrusion detection based on heterogeneous attributes is proposed in this paper. Firstly, the algorithm modifies the comparability measurement for the categorical attributes according to the formula of Hemingway;then, for the shortages of fuzzy C-means clustering algorithm: initialize sensitively and easy to get into the local optimum, the presented new algorithm is optimized by GuoTao approach. We simulate our algorithm with the KDDCUP99 data set, and the results show that the convergence rate of the new algorithm is faster than the original fuzzy C-means clustering algorithm and the performance of our algorithm is more stable. © 2012 ACADEMY PUBLISHER.

In the problem of domain transfer learning, we learn a model for the prediction in a target domain from the data of both some source domains and the target domain, where the target domain is in lack of lab.ls while the source domain has sufficient lab.ls. Besides the instances of the data, recently the attributes of data shared across domains are also explored and proven to be very helpful to leverage the information of different domains. In this paper, we propose a novel learning framework for domain-transfer learning based on both instances and attributes. We proposed to embed the attributes of different domains by a shared convolutional neural network (CNN), learn a domain-independent CNN model to represent the information shared by different domains by matching across domains, and a domain-specific CNN model to represent the information of each domain. The concatenation of the three CNN model outputs is used to predict the class lab.l. An iterative algorithm based on gradient descent method is developed to learn the parameters of the model. The experiments over benchmark datasets show the advantage of the proposed model. Copyright © 2018, The Authors. All rights reserved.

At present, network information audit system is almost based on text information filtering. Text categorization is the basic technology of text information filtering. Pattern matching algorithms are very important for the rule based information audit system. It directly influences the accuracy and real-time performance of the system. The KMP and BM algorithms are introduced in this paper. Research is carried out to improve the BM algorithm and a better BM algorithm is proposed According to the situation that the system characters group is bigger and that characters of the pat tern are less, the thesis puts forward an improved string-matching algorithm. The results of our experiments prove that it promotes the precision of text categorization. © 2008 Binary information Press.

Recently, Authentication protocol has been recognized as an important factor for grid computing security. This paper described a new simple and efficient Grid authentication system providing user anonymity. Our system is based on hash function, and mobile users only do symmetric encryption and decryption. In our system, it takes only one round of messages exchange between the mobile user and the visited network, and one round of message exchange between the visited network and the corresponding home network. The proposed architecture possesses several desirable emerging properties that enable it to provide an improved level of security for grid computing systems..

Multimodal fusion has become an important research technique in neuroscience that completes downstream tasks by extracting complementary information from multiple modalities. Existing multimodal research on brain networks mainly focuses on two modalities, structural connectivity (SC) and functional connectivity (FC). Recently, extensive literature has shown that the relationship between SC and FC is complex and not a simple one-to-one mapping. The coupling of structure and function at the regional level is heterogeneous. However, all previous studies have neglected the modal regional heterogeneity between SC and FC and fused their representations via "simple patterns", which are inefficient ways of multimodal fusion and affect the overall performance of the model. In this paper, to alleviate the issue of regional heterogeneity of multimodal brain networks, we propose a novel Regional Heterogeneous multimodal Brain networks Fusion Strategy (RH-BrainFS). Briefly, we introduce a brain subgraph networks module to extract regional characteristics of brain networks, and further use a new transformer-based fusion bottleneck module to alleviate the issue of regional heterogeneity between SC and FC. To the best of our knowledge, this is the first paper to explicitly state the issue of structural-functional modal regional heterogeneity and to propose a solution. Extensive experiments demonstrate that the proposed method outperforms several state-of-the-art methods in a variety of neuroscience tasks. The codes are availab.e at https://***/Yedaxia1/RH-BrainFS.

Automatic categorization of bioscience literature containing QTL information

In this paper we introduce text categorization methods to address the classification problem of literature containing Quantitative Trait Locus, QTL information. Our work focused on building an automatic categorization system targeting the QTL information of various species based on Support Vector Machines, SVM. A text representation strategy is proposed combining words and phrases that effectively improve the classification accuracy. Through studying literature containing QTL information and other species-related publications, we determined representative phrases and detected abbreviations in order to form another set of features. Together with the words selected by Chi value, the two sets of features were both used to represent text samples. We employed a portion of particular species’ QTL-related literature data to conduct an experiment regarding the system’s construction, and then tested our system using the data of multiple plants and species. The experiment results indicate that our work may help further research on constructing QTL information databases. © 2016, UK Simulation Society. All rights reserved.

A peer selection prior data scheduling method for peer-to-peer media streaming system

引用

Beijing Gongye Daxue Xuebao/Journal of Beijing University of technology 2010年第SUPPL. 1期36卷 26-30页

作者： Ji, Qi-Jin Yang, Zhe Zhu, Yan-Qin School of Computer Science and Technology Soochow University Suzhou 215006 Jiangsu China Provincial Key Laboratory for Computer Information Processing Technology Soochow University Suzhou 215006 Jiangsu China

Data Scheduling in P2P media streaming system considers which peer to select for interesting media data. Since data scheduling decision can only be made in terms of the local information of each peer, the commonly used data block selection prior data scheduling is prone to traffic concentration to minor peers in the system and thus degrades the system throughput greatly. A peer selection prior data scheduling method is proposed in this paper, which can direct traffic to the neighbors evenly. The simulation results show that the proposed method can mitigate the load of source server more than 25% and meanwhile improve the system throughput comparing with the data block selection prior alternatives.
