Application of Improved PSO - BP Neural Network in Customer Churn Warning

Endpoint Prediction of BOF Steelmaking based on BP Neural Network Combined with Improved PSO

This paper concerns the endpoint estimation of the basic oxygen furnace (BOF) steel making process. More specifically, a back propagation (BP) neural network is employed to estimate the endpoint carbon content and the endpoint temperature of BOF, and an improved particle swarm optimization (PSO) algorithm is proposed to optimize the prediction model for improving the accuracy of the endpoint pr...

Application of Improved BP Neural Network in Controlling the Constant-Force Grinding Feed

BP neural network is applied to control the amount of feed, which is the key problem during the constant-force grinding. Firstly, BP neural network is constructed. Because its convergence is slow and local minimums often occur, the adaptive learning rate is used and certain momentums are added to improve BP neural network. Then the feature parameters in time and frequency domain are picked up i...
