This paper proposes a novel algorithm of nodes partition for the Ad Hoc network mode. Firstly, we adopt Man Road sub-cluster algorithm to discuss the clustering for a square region with 926 random nodes. Secondly, we establish the central moving model based on the simulated annealing algorithm and the least circle overlay model, which are used to remove the redundancy of the circle number and the...
There are relevance and redundancy of the feature words in the text vector space, so we proposed a text-reducing method based on the improved KNN algorithm in this paper. Vector polymer theory and feature selection methods were used to reducing the dimension of vector space. Feature words would have more ability to represent categories after feature selection. Experiments proved, the improved KNN...
