【摘要】 人体体质各测试指标与人体综合体质之间存在着复杂的非线性关系 ,为了客观准确的评价人体体质的综合水平 ,选取体质各测试指标作为输入 ,基于体质研究专家经验的体质综合评价结果为期望输出 ,引入人工神经网络BP网络模型建立了体质综合评价模型。实际应用结果表明 ,所建立的体质综合评价模型拟合精度高 ,评价效果好 ,能较真实地反映人体体质的综合水平。更多还原

【Abstract】 BP network model of the artificial nerve network was introduced to do the quantitative research to the comprehensive evaluation of human body constitution. In view of complicated and nonlinear relation between constitution items and body comprehensive constitution, the constitution items were taken as the input and the expert’s comprehensive evaluation of human body constitution was taken as a desired output for modeling the comprehensive evaluation of human body constitution. The modeling result indicated that the BP network model not only has high precision of fit, but also has good prediction effect. BP network model can really reflect the comprehensive constitution of human body. A new approach for the quantitative research of the comprehensive evaluation for human body constitution was provided.更多还原
