Abstract:Traditional recommendation system has the problem of sparse user ratings and system scalability. This paper proposes a recommendation system based on intelligence multi-agent. At first, the cosine similarity measure has been used to handle user-item rating matrix, thus the initial neighbor set for target users can be gained. Then, user ratings have been mapped to relevant item attributes for generating user-attributes value preference matrix UPm of each user. Thus, user similarity can be computed based on UPm and rating sparsity has been alleviated simultaneously. The recommendation system of intelligence multi-agent makes calculating an online processing, and thus improves the system scalability. Experimental results show that the new system achieves a better accuracy in recommended convergence.

Abstract:Along with tobacco information system region centralism and data centre establishment, data concentrate gradually. Being lacking in different data disaster backup functions, the system based on the EMC array and the Veritas Storage Foundation cannot satisfy the present informationization safety requirements. On the basis of investigations and studies in Zhejiang Province, this paper designs 2 disaster backup plans: different migration and additional computer. Different migration plan is to separate the storage device from the present computer and put them in two different engine rooms. Additional computer plan does not change the original computer room, but adds new computer and storage device in the new computer room. In practice, these two schemes can protect the original investment and solve the problem of disaster backup.

Abstract:More and more applications are developing from desktop to networking in present WEB2.0 era. The content of the network gradually shifts from the original static hyperlink to a series of variegated applications including electronic commerce, electronic mailing, game recreation, digital media, which all can be loaded onto the browser. However, with the constant development of browser platform many hidden dangers concerning safety have arisen. For instance, a series of hacker methods such as Xss, xsrf (cross-site request forgery), DNS have become hidden threats to internet users. Hackers could steal users' personal information by utilizing malicious code or through phishing site, which may cause great economic loss. This paper aims to analyse Xss(cross site scripting) attack, and comes up with a new framework to solve this increasingly apparent safety problem.

Abstract:The traditional genetic algorithm has the shortcomings of premature convergence and slow convergence. This paper adopts improved niche technology to solve this problem. It also uses the specific issues to improve the genetic operators, and the improved niche genetic algorithm is applied to Clustering Mining. As the K-means algorithm in the clustering algorithm for mining has the problem of the selection of the initial value of K-senstive and if we select a different value, it will lead to a different clustering result. It is easy to fall into local optimum. So it will make poor clustering results. Therefore, this article combines the improved niche genetic algorithm with K-means algorithm to produce a new improved algorithm named an improved niche genetic clustering algorithm. It is verified that the algorithm is valid in improving the quality of clustering analysis.

Abstract:Firstly, the key feature points which have much less reaction under changing appearances are captured from a tested face. Then the transforming vectors between the relative coordinates of the captured points and each corresponding point in the face model are used to estimate the pose of the tested face. At last, a synthetical face shape model is established by using the captured points and the estimated pose vector. The shape model would be robust under changing appearances and poses because the points in the model are unchangeable under different appearances. In addition, this paper estimates the pose of the tested face correctly. The shape model will be fit for face recognition.
