| Abstract: | Aiming at problems of great difficulties and low precision in predicting critical deposition velocity of slurry pipeline,a prediction model for critical deposition velocity based on particle swarm optimization and extreme learning machine(PSO-ELM)is proposed. The method using PSO algorithm to optimize the ELM model parameters such as the input weight and hidden element bias,the optimized ELM model is used to predict prediction set. The maximum error of predicted result is 5. 73% by experimental simulation,which shows that the prediction effect is superior to the conventional ELM and back propagation(BP)neural network model. |
