In this paper, a variable-length counting Bloomfilter is studied for a variable-length-count Bloom filter(VLCBF) when configuring updates to the median groupfrequently-shifting. Our proposed improved VLCBF deleteseach hash value stored in the first buffer insertion. Only theauxiliary Bloom filter bit is modified accordingly until thebuffer is full when the group of digits updates a shift. Themethod...
With the development of computer network technology, network security issues become increasingly more serious, firewall technology is one of the most effective methods to protect network security. Stream filter technology is a new firewall technology, which not only can supervise the network layer as packet filtering firewall, but also can supervise transport layer and application layer as the application...
Compared with the traditional data mining system algorithms library, the introduction of Web Service technology into data mining system algorithm library realizes the separation of data, algorithm and interface. The loose and interconnected mode greatly reduces the complexity of the development for the algorithms library in data mining system and is convenient for the dynamic management of data mining...
In the management of the online public opinion and Internet intelligent information, people need to obtain the content of the forum threads for further research on the topic emotion and the dissemination of forum topics. This paper presents a method based on templates to extract web forum contents. Proposed method overcomes the problem which caused by the change of the web pages structures and contents,...
Dictionary mechanism is the basis of Chinese word segmentation, and its quality directly affects the speed and efficiency of Chinese word segmentation. In existing dictionary mechanisms, there are such shortages as space wasting, low efficiency, and difficult maintenance, and therefore, how to establish an effective mechanism is an urgent problem for Chinese word segmentation. In this paper, the idea...
Aiming at the bug that the conventional ESPRIT algorithm can not estimate coherent signals, a new ESPRIT algorithm is proposed based on the modified singular value decomposition algorithm (MSVD). This new ESPRIT algorithm first processes the data from the array X with MSVD, gets the data covariance matrix R, and next conducts singular value decomposition of R to get the signal subspace and carries...
