【Abstract】 Improved BP neural network which adopted Lev-enberg-Marquardt optimized algorithm has been used to predict thickness. In this algorithm, the parameter μ can be adaptive adjusted, and network convergence speed is higher than before. Thickness predicting precision was improved. A new precise and high efficiency way for cold continuous rolling exit thickness prediction have been provided.更多还原
