In order to improve the clustering quality of the Affinity Propagation algorithm further and get more accurate number of clusters, this paper proposed a novel algorithm based on the Particles Swarm Optimization, which used In-Group Proportion index as fitness function to search the optimal preference of Affinity Propagation algorithm. Experimental results show that the predicted results had been tested...
This paper designs a packaging structural of six-chip white LED down light with a total power of 15 W. The highest temperature of LED chip is 110.5°C, and the temperature of heat sink is 71.6 °C ∼73.2°C by finite element method (FEM). The experimental data are obtained by the thermocouple, with forward current of 700-mA at the ambient temperature of 35°C. The relative error between the simulation...
Particle Swarm Optimization combines with Munkres algorithm is proposed for Point Pattern Matching in three dimensions. Point Pattern Matching is a fundamental aspect of many fields in computer vision and pattern recognition. The point pattern matching technique could be described as finding an optimal transformation for one point pattern to the other under some measures. The proposed algorithm can...
A novel parallel approach to run standard particle swarm optimization (SPSO) on Graphic Processing Unit (GPU) is presented in this paper. By using the general-purpose computing ability of GPU and based on the software platform of Compute Unified Device Architecture (CUDA) from NVIDIA, SPSO can be executed in parallel on GPU. Experiments are conducted by running SPSO both on GPU and CPU, respectively,...
