Particle Swarm Optimization(PSO)is introduced in the field of dam monitoring
and then a new dam monitoring model based on PSO Neural Network(PSONN)is put forward. The model makes full use of the global optimization of PSO and local accurate searching of BP Neural Network(BPNN)to provide better initial weights for BPNN. Seriatim PSONN(SPSONN)model
Whole PSONN(WPSONN)model
Seriatim BPNN(SBPNN)model and Whole BPNN(WBPNN)model are compared here
the results show that the seriatim prediction models are superior to those whole models with higher forecast precision. Furthermore
the PSONN models exhibit faster convergence rate
less iterative number and better forecast precision than the BPNN ones. Especially
the SPSONN model is more efficient to satisfy the demand of real-time prediction of dam monitoring.
