Abstract：According to the insufficiency existed in traditional BP algorithm for sales forecast such as low learn rate,low convergence and falling into local optimization, etc,the improvement measures are proposed. The effectiveness and the convergence of the algorithm are improved by self-adapted learning rate, the adaptability is improved by the additive momentum, and the weight of neural network is optimized by modified genetic algorithm. The large-scale search optimum ability of modified genetic algorithm is used to implement the purpose of fast search optimum and accurate prediction. Finally, an example verifies this algorithm.
