Cross domain data such as numerical or categorical types are ubiquitous in practical network. Network anomaly detection based on cluster analysis exist some difficulties, for example, the initial center of cluster analysis is sensitive and easy to fall into the local optimal solution. Cross domain data involved great information, but can't be effectively used, which will influence the performance...
For managing spectrum effectively in cognitive radio system, a matching game algorithm for spectrum allocation based on POMDP model is proposed. Cognitive users can maximize reward of system through observation statistics of historical information, and adjustment their matching strategy. The simulation results show that the approach realizes efficient allocation of the spectrum resource.
In this paper, an improved select space multi-objective particle swarm optimization was proposed based on the study on particle swarm optimization algorithm for solving multi-objective optimization. The method applied an improved quick sort method to construct the non-dominated solution set. The upper limit of the non-dominated solution select space was set. At the same time, the optimal solution...
An update dynamic programming algorithm is presented in allusion to the features of the moving infrared small dim target. The main idea of this algorithm is that the predicting states between frames and a low threshold are applied to reduce the computation. The background noise is suppressed by the image pre-processing. The probability of detecting and false alarm are used to determine the threshold...
Concurrent objects are notoriously difficult to design correctly, and high performance algorithms that make little or no use of locks even more so. In this paper, we present a formal verification of a lazy concurrent list-based set using model checking techniques. The algorithm supports insertion, removal, and membership testing of a list entry under optimistic locking scheme. The algorithm has nonfixed...
Under a unexpected disaster, The fundamental purpose of emergency evacuation is to take a scientific and effective evacuation strategy to maximize the population of the evacuation of the affected in the shortest time, and in which, the construction of evacuation routes and the distribution of evacuation intersection flow is the key of the realization of this purpose. In this paper, aiming at the problem...
