A valid multiscale classification method of synthetic aperture radar (SAR) imagery is proposed based on Multiscale technology and Markov Random Field (MRF) mode. Firstly, we employ multiscale autoregressive model for extracting the feature of SAR image. which is modeled by Markov Random Field (MRF) Model that relies on the Gaussian distribution. Secondly, using the joint probability distribution in terms of an energy function, estimation of parameters can be performed by the stochastic relaxation algorithm. Then the maximum posteriori (MAP) is designed as the optimal criterion and the final labels are obtained by the simulated annealing algorithm. Experimental results show that this method is accurate, efficient and robust. © 2009 IEEE.

This paper presents a neural network proportion integral differential (PID) controller for automatic gauge control (AGC) system of rolling mill, it is an high non-linear and time-varying system. The traditional PID controller has the invariable parameters. However in the actual factory, the environment of the controlled object is often changed. If the three parameters of PID controller can't adjusted adaptively, the controller will have a badly control effect. The neural network can adjust the three parameter based on the control error. If the control error becomes zero, the parameter didn 't adjust too. The simulation shows that neural network PID controller has good dynamic quality. The control system has short response time, small over modulation, highly steady state behavior and robustness comparing with the traditional PID controller. © 2009 IEEE.

The recommendation system is a significant field to solve the problem of information overload today. However, the recommendation system relies heavily on the user's behavior information, which is easy to suffer attacks. Therefore, how to prevent the recommendation system from effecting by the attacks is a major issue in the research field of protection recommendation system. In response to the above questions, we found that the shilling attack has the features of short rating history, large number of rating and other potential features compared with normal user profiles. Therefore, we propose a neural network structure to learn the latent features between users and items and we construct shilling attack detection model based on neural network. The experimental results show that the detection method of this paper has achieved the expected goal. © 2019 IEEE.

An intelligent home system is designed and implemented based on the context-awareness technology, which minimizes users' interventions and maximizes functional autonomy of systems. A multi-agent technology is proposed based and service oriented approach to build our middleware which supports tasks including acquiring, discovering, interpreting, reasoning, accessing various contexts and interoperability between different context-aware systems. In order to simplify the design of our middleware and make it convenient for users, a third-party, "Internet service providers", is proposed which is responsible for the service updating and service composition. © 2009 IEEE.

Database watermarking plays an irreplaceable role in copyright authentication and data integrity protection, but the robustness of the watermark and the resulting data distortion are a pair of contradictory objects that cannot be ignored. To solve this problem, a reversible database watermarking method, named IGADEW, is proposed to balance the relationship between them. The biggest difference from previous research is that IGADEW synthesizes the optimization objects and obtain various parameters through genetic algorithm (GA). Second, the fitness function considers the weights of robustness and distortion, aiming to find the optimal balance between the two. IGADEW uses the Hash-based Message Authentication Code (HMAC) algorithm to encrypt the experimental parameters and uses the primary key hash algorithm for data grouping, both to ensure robustness. And the data distortion is limited with the help of threshold constraints. Finally, experiments using the UCI dataset demonstrate the effectiveness of IGADEW. Experimental results show that, compared with existing methods, IGADEW is more robust against common attacks, with lower data distortion. © 2023 IEEE.

Effcient Distributed Skyline Queries for Mobile Applications

Journal of computer Science & Technology 2010年第3期25卷 523-536页

In this paper, we consider skyline queries in a mobile and distributed environment, where data objects are distributed in some sites （database servers） which are interconnected through a high-speed wired network, and queries are issued by mobile units （laptop, cell phone, etc.） which access the data objects of database servers by wireless channels. The inherent properties of mobile computing environment such as mobility, limited wireless bandwidth, frequent disconnection, make skyline queries more complicated. We show how to efficiently perform distributed skyline queries in a mobile environment and propose a skyline query processing approach, called efficient distributed skyline based on mobile computing （EDS-MC）. In EDS-MC, a distributed skyline query is decomposed into five processing phases and each phase is elaborately designed in order to reduce the network communication, network delay and query response time. We conduct extensive experiments in a simulated mobile database system, and the experimental results demonstrate the superiority of EDS-MC over other skyline query processing techniques on mobile computing.

A new clustering classification approach based on fuzzy closeness relationship (FCR) is studied in this paper. As we know, fuzzy clustering classification is one of important and valid methods to knowledge discovery. One of problems in fuzzy clustering classification is to determine a certain fuzzy sample classification in given limited sample space. Another is its validity, that is to say, if the sample is resemble in sample space, its fuzzy type will be resemble too. In our research, firstly, using triangle arithmetic operator and triangle transference, we extend fuzzy equivalence relationship to fuzzy closeness relationship, and cluster. Secondly, importing fuzzy coverage based on fuzzy closeness relationship, we judge resemble type of resemble sample. Thirdly, we introduce the clustering classification method based on fuzzy closeness relationship and fuzzy coverage. The method can overcome information more loss in fuzzy equivalence. Finally, we test its feasibility. The approach is applied to knowledge discovery for risk prediction of electronic commerce market, good result has been gotten. ©2010 IEEE.

In this paper, we propose an effective multi-object tracking system which can handle the partial occlusion in the tracking process. First, this method employs the part-based model to localize the person and body parts in every frame. Then it leverages the motion characteristics of both parts and the entire body to generate the trajectories of individuals. To overcome the difficulty in partial occlusion, we propose to formulate the task of multi-object tracking into multi-object matching with body part cues. The large scale comparison experiment on the popular tracking datasets demonstrates the superiority of the proposed method. © Springer-Verlag 2013.
