Recent attempts to assess the performance of SSVM algorithms for unconstrained minimization problems differ in their evaluations from earlier assessments. Nevertheless, the new experiments confirm earlier observations that, on certain types of problems, the SSVM algorithms are far superior to other variable metric methods. This paper presents a critical… (More)
With e-commerce growing rapidly, online product reviews open amounts of studies of extracting useful information from numerous reviews. How to generate informative and concise summaries from reviews automatically has become a critical issue. In this paper, we present a novel unified graph model, composited information graph (CIG), to represent reviews with… (More)
The paper built the architecture of data mining algorithms library module based on Web Service, analysed the composition of the algorithms management module and its correlation with several modules, developed a data mining algorithms library system of modularization and hierarchy with Web Service on the basis of the logic frame of Meta data management.
In order to overcome the seriously constrained storage and processing problem of a single node in wireless multimedia sensor networks (WMSNs), distributed Wyner-Ziv image compression algorithm is brought forward based on Wyner-Ziv. In this paper, the pixel domain Wyner-Ziv video coding scheme is adopted to achieve the distributed video codec system, the… (More)
—To achieve the fast mapping between the higher-layer protocol data unit and the connection, we propose a packet convergence sublayer classification algorithm according to IEEE Std 802.16 standard. The algorithm firstly constructs non-collision hash function based on port numbers and protocol values, then divides the source IP address and destination IP… (More)
