摘要
人工神经网络模拟大脑的认知功能,通过改变连接点的权值和阈值来训练神经网络完成特定的功能。运用基于遗传算法的BP网络模型,以国家大气质量标准作为网络的输入样本对网络进行训练,对某地区大气质量进行评价,结果与综合指数法比较吻合。
Cognition function of brain was simulated by artificial nerve network by changing threshold limit value of linking point. BP network model based on genetic algorithms was used to assess air quality in some area with national air quality criteria as inputting samples of the network. The results were in conformity with comprehensive index method.
