An Improved BP Algorithm Based on the Nonlinear Least Square Method and Application in Congestion Control

The standard back-propagation(BP) algorithm converges slowly and is ease to trip into local minimum, which is the main reason why it cannot be used widely in practical applications. Therefore, a new BP algorithm based on the nonlinear least square method was put forward in this paper. The convergence stability was enhanced by adding the positive matrix in Hessian Matrix. The results have proved that the new algorithm can converges very fast and avoid tripping into local minimum. The improved BP algorithm is used in congestion control of the computer network in order to solve the congestion of network. The data of simulation experiment demonstrate the proposed control scheme is scalable and efficient, and has good network performance.
