This paper applied Multi-Agent to E-commerce personalized Recommender System, and designed E-commerce personalized Recommender System based on Multi-Agent, namely, MAPRS. Off-line recommendation and on-line hybrid recommendation are used to construct the core recommender model under the intelligent control. The paper presents the function and design ideas of various components of the system.
To estimate carrier frequency offset, a polynomial-rooting algorithm is proposed for symbols with constant modulus in OFDM systems. This algorithm makes use of the orthogonal subspace of the squared spectrum vector of the channel. Among the group of non-iterative methods, the algorithm offers the best accuracy.
To estimate carrier frequency offset, a polynomial-rooting-and-evaluation algorithm is proposed for symbols with constant modulus in OFDM systems. This algorithm makes use of the orthogonal subspace of the squared spectrum vector of the channel. The algorithm improves an existing non-iterative method.
The characterization of the access structures of ideal secret sharing schemes is one of the main open problems in secret sharing and has important connections with matroid theory. In the EUROCRYPT'07, Farras made a important contribution to this work by using discrete polymatroids. In particular, they further gave a very difficult open problem, that is, characterizing the representable discrete polymatroids,...
Web forum has become an important resource on the Web due to its rich information contributed by millions of Internet users every day. Meanwhile, thousands of junk or valueless messages exist in Web forum. Recognizing high-quality topics should be fundamental tasks in search engine and Web mining systems. However, it is not a trivial problem to quantify high-quality topics on web forum. Users face...
Feature selection attracted much interest from researchers in many fields such as network security, pattern recognition and data mining. In this paper, we present a wrapper-based feature selection algorithm aiming at modeling lightweight intrusion detection system (IDS) by (1) using modified random mutation hill climbing (MRMHC) as search strategy to specify a candidate subset for evaluation; (2)...
