BP人工神经网络是一种基于误差反向传播算法(BP算法)的多层前向人工神经网络,由信号的正向传播与误差的反向传播两个过程组成。应用BP人工神经网络对军事工程投资效益进行评价,可先提出军事工程投资综合评价指标及评价指标体系,然后构建模型,之后对人工神经网络模型进行训练和测试,验证模型的有效性和实用性。
BP artificial neural network is a multi-layer forward artificial neural network based on error back propagation algorithm (BP algorithm). It consists of two processes: signal forward propagation and error back propagation. BP artificial neural network is used to evaluate the investment efficiency of military engineering. The comprehensive evaluation index and evaluation index system of military engineering investment can be put forward first, and then the model is built. Then, the artificial neural network model is trained and tested to verify the validity and practicability of the model .
