Particle swarm optimization (PSO) algorithm has attracted great attention as a stochastic optimizing method due to its simplicity and power strength in optimization fields. However, two issues are still to be improved, especially, for complex multimodal problems. One is the premature convergence for multimodal problems. The other is the low efficiency for complex problems. To address these two issues,...
A node position derivation algorithm called IR for WSNs is developed in this paper. IR is an iterative algorithm based on node-beacon distance information. It is assumed that each sensor node can connect with several beacons by one-hop or multihop and estimate the node-beacon distances, and then, the algorithm is executed in a distributed mode. Simulation is provided to compare our proposed algorithm...
The paper presents a support vector machine based Part-Of-Speech tagging on Chinese database which is part of our speech synthesis system. The model can be classified as SVM model and uses many sequential features to predict the POS tag. The text database was download from the internet with 1,280,000 words and 33 parts of Speech. The total accuracy of our experiments is 99.31%.
