Disadvantages inherent to existing guidance systems for scenic areas can be reduced to a partial point traversal problem in the connected graph. This paper presents an intelligent, ant-colony-based path planning algorithm that is applicable to scenic areas. The proposed algorithm modifies the ants’ ending tour to achieve partial point traversal of the connected graph by eliminating the restriction...
The functional connectivity of brain is a key point of brain network analysis. The BOLD (blood oxygen level dependent) fMRI (functional magnetic resonance imaging) signal is an effective projection signal of brain function. A dynamic method in resting-state (RS) functional connectivity analysis of brains is proposed in this paper. In contrast to traditional static method, a sliding window is used...
According to the actual requirements of telecommunications enterprises customer segmentation, in this paper an improved K-Means algorithm was introduced. The algorithm was used to initialize cluster center in the cluster analysis phase of Data Mining technology. The experimental results proved that the novel algorithm has greater improvement than the original one in efficiency and accuracy. The results...
In this paper, we presented a new hybrid particle swarm optimization algorithm which is used to design the control unit of an adaptive polarization mode dispersion compensation. Comparing with the conventional particle swarm optimization algorithm, the new algorithm converges to the global optima much faster than the conventional particle swarm optimization algorithm. Experiments show that the new...
The efficiency of subscription subsumption checking remains a key issue for content-based publish/subscribe systems. In this paper, we propose an efficient data structure called subscription subsumption graph (SSG). This data structure could differentiate the two types of subsumption relationships and help speed up the process of subsumption checking and subscription cancellation. We then present...
