An Improved Particle Swarm Algorithm and Its Application in Soft Sensor Modeling

An improved PSO(particle swarm optimization) algorithm is presented which well addresses slow convergence speed and low calculation precision in the basic PSO algorithm.By comparing and analyzing the results of several standard test functions,the excellent performance of PSO is proved.Then,the improved PSO is applied to optimization of the structure and parameters in NN(neural network).The availability of algorithm in optimizing neural network is proved by applying NN in soft sensor modeling of 4-CBA measur...
