摘要
准确预测未来我国煤炭产量对保持我国煤炭供求平衡具有重要的指导意义。本文讨论了BP神经网络及其改进算法,提出了一种采用L-M算法的改进BP神经网络的非线性系统预测模型,并将其用于煤炭产量预测中,通过具体的仿真及实践结果验证了改进BP的有效性。
This paper introduces BP neural network, its improved algorithm and a non - linear- system forecasting model based on L - M algorithm, whose effectiveness has been testified and which will be widely used in coal output forecast by artificial and practical experiment.
