With the coming era of astronomic data with mass, high dimensionality and nonlinearity, clustering astronomic data becomes more and more important. This paper proposed a new clustering algorithm, which reduces the space and time complexity and the sensitivity to the parameters. It is suitable for processing large scale astronomic data sets. The new algorithm consists of three phases: coarsening clustering,...
The space complexity of Affinity Propagation (AP) clustering algorithm is high, and it is difficult to be applied to image processing problem directly. In order to overcome this shortcoming, this paper proposes a gray image segmentation method based on gray level histogram and AP clustering algorithm, named GLHAP. In the proposed algorithm, in order to decrease the input data of algorithm AP, only...
This paper proposed a new algorithm of Chemical Molecules search based on graph similarity measure. The similarity score between graphs is defined based on the weights of sets of connected subgraphs. It uses the feature-graph matrix to construct index structure. Experimental result shows that the proposed Chemical Molecules search algorithm is effective.
