A user identity matching method based on integrating account attributes

Journal of Physics: Conference Series 2018年第3期1087卷

作者： Y Z Yang H T Yu r Y Huang National Digital Switching System Engineering & Technological R&D Center Zhengzhou China

Aiming at the low utilization rate of attribute information and the lack of mining of the correlation among attributes of the existing cross-social network user identity matching algorithms, we proposed an algorithm for user identity matching across social networks utilizing fuzzy measure and Choquet integrals. Firstly, according to the characteristics of different attributes, we determined different similarity calculation strategies; Secondly, we utilized particle swarm optimization method to calculate the fuzzy density of each attribute; Then Choquet integral was utilized to calculate the similarity of two accounts; Finally, the similarity was compared with the preset matching threshold and the final matching result was obtained. The experimental results in multiple sets of data showed that the average F1 value of the proposed algorithm reaching 84.5%. The performance is not only better than traditional machine learning methods, but also better than several baseline algorithms. It can be more accurate to identify the same user's accounts in multiple social networks according to the attribute information.

In recent years, SdN(Software defined Network) as a new network architecture has become the hot research point. Meanwhile,the well-known Open Flow-based SdN got a lot of attention. But it can't provide a flexible and effective network resource description *** an open programmable technology, For CES(Forwarding and Control Element Separation)has also been concerned. However, For CES is confined within a single network node and cannot be applied to the entire network. This paper proposes a new architecture — ForS A(ForC ESbased SdN architecture). The architecture is added a configuration layer based on the traditional SdN architecture, which solves the problem that the northbound interface is not clear between the application layer and the control layer in the SdN architecture. ForS A also implements the compatibility within various forwarding devices in the forwarding layer.

To address the issues that middleboxes as a fundamental part of today's networks are facing, Network Function Virtualization(NFV)has been recently proposed, which in essence asserts to migrate hardware-based middleboxes into software-based virtualized function *** to the demands of virtual services placement in NFV network environment, this paper models the service amount placement problem involving with the resources allocation as a cooperative game and proposes the placement policy by Nash Bargaining Solution(NBS). Specifically,we first introduce the system overview and apply the rigorous cooperative game-theoretic guide to build the mathematical model, which can give consideration to both the responding efficiency of service requirements and the allocation *** a distributed algorithm corresponding to NBS is designed to achieve predictable network performance for virtual instances ***, with simulations under various scenarios,the results show that our placement approach can achieve high utilization of network through the analysis of evaluation metrics namely the satisfaction degree and fairness index. With the suitable demand amount of services, the average values of two metrics can reach above 90%. And by tuning the base placement, our solution can enable operators to flexibly balance the tradeoff between satisfaction and fairness of resourcessharing in service platforms.

In this paper, we present a meander-line monopole antenna for Unmanned Aerial Vehicle (UVA). In order to improve the resonant characteristic and expand the bandwidth, a couple of coupled patches have been added. It also improves the radiation characteristics in higher frequency. The antenna realizes omni-directional radiation in the horizontal plane when operating in780MHz-900MHz and 1.20GHz-2.28GHz. The antenna is conformed on the side of airframe and can be widely used as communication antenna on UVAs for its performance of dual-band and wideband. © 2016 IEEE.

Image segmentation can be used in non-destructive testing, tracking and recognition. Level set method for image segmentation has poor performance on efficiency. In this paper, we propose to use max-flow algorithm to optimize a locally improved Chan-Vese model for image segmentation in the presence of intensity inhomogeneity. The energy function of local Chan-Vese model is introduced firstly. This model consists of global term, local term and penalty term and the local term contributes the segmentation for images with intensity inhomogeneity. Then, we convert this energy function to the frame of Graph Cut whose energy function can be efficiently minimized by max-flow algorithm. As a result, the process of optimization of local Chan-Vese model can be accelerated by using max-flow algorithm. The experiments demonstrate that the proposed method can achieve satisfactory segmentation for images with intensity inhomogeneity as well as very high efficiency. © 2016 IEEE.

As the technology scales down, the single-event transient(SET) has become a great concern for the reliability of integrated circuits(ICs). A novel time redundant flip-flop structure is proposed to detect and correct the SET pulse. The most advantage of this structure is that it has very little setup and hold time overhead and the architecture need not be modified to recover the system. HSPICE simulation is adopted verify the validation of this structure. Finally, we give the use of this flip-flop in the pipeline based architecture.

To predict the radiation emission of the FPGA, the radiation emission model for the chip is proposed with ICEM and the simulation result is also presented in this paper. The linear near-field surface scan system (LNFS) following electromagnetic compatibility standard is applied to measure the emission. It is illustrated that the simulation results agree with the measurements, so the value of the model for practical application is verified.

In order to effectively identify and extract the red signal from the leakage signal in the computer's power line, a method based on particle swarm optimization (PSO) is proposed to optimize the multi classification support vector machine (SVM). Firstly, the conductive leakage signal is filtered. Then the SVM penalty parameter and kernel parameter are optimized by PSO, the conduction leakage signal is trained and classified. Finally, the classification performance of the un-optimized SVM is compared with PSO-SVM. The result shows that this method has higher classification rate than the grid search method. The classification and recognition rate reaches 87.23%.
