According to characteristics of particle swarm optimization algorithm, a novel particle swarm optimization algorithm based on adaptive space mutation (ASM-PSO) is proposed. During the searching process, the convergence speed and globally convergence ability is greatly improved by the adaptive space mutation based on the variance of the population's fitness. Experiment results show that the new method,...
Adequate penetration is a basic property of qualified welds. The proposed monitoring system was constructed to classify the welding state as adequate penetration or inadequate penetration by using infrared, ultraviolet and sound sensors. In order to achieve a smooth data acquisition and a quick response of the system, the circular buffer technology and multithreading/multitasking technology were applied...
An improved particle swarm optimization is used to train ridgelet neural network instead of the traditional gradient algorithms. Firstly, the model of ridgelet neural network and the traditional particle swarm optimization (PSO) algorithm are briefly described. Secondly, an improved particle swarm optimization with self-adaptation mutation factor is proposed. Then the improved particle swarm optimization...
