摘要
文中介绍了自适应调整学习率的改进BP算法 ,建立了适用于围岩稳定性分级评价和模式识别的BP神经网络模型 ,编写了相应的MATLAB计算程序。应用示例表明 。
In this paper,an ameliorated arithmetic for back Propagation network(BP) of self adapt and self adjust learning ratio is introduced.The BP model for the wall rock stability classification evaluation and pattern identification is established.MATLAB(MATrix LABoratory) program is compiled.It is verified by samples that the BP model has nice identifyimg and evaluating effect.
