P2P network is short of authentication, so the CPK (Combined Public Key) authentication mechanism and DHT (Distributed Hash Table) algorithm in P2P network are researched, and CPK authentication is used in structure P2P network for its security. At point, the series-Hash method combines both DHT algorithm of structure P2P network and peers' authentication. Then base on cluster partition P2P network,...
In the underdetermined blind source separation and sparse component analysis, we get sensor signals. The mixed matrix and source signals aren’t known, where the number of sensor signals less than that of source signals, but we can know source signals are sparse, so we use the information to recover source signals by estimating the mixed matrix. This paper gives an algorithm for estimating mixed matrix...
Based on the actual needs of project, this paper introduces a solution of cluster centers and attached matrix into application of Fuzzy C-means clustering algorithm in macro-economic forecast. We present the specific implementation of this algorithm, as well as the major steps of data mining. And in the end, an example is given to prove the solution’s effectiveness in macro-economic forecast.
Iterative search margin based algorithm (Simba) has been proven effective for feature selection. However, the previously proposed model does not effectively utilize the structure information hidden in data which may have a great impact on the generalization performance of post-analysis classifiers. In this paper, we introduce a novel hypothesis-margin model incorporating structure information for...
