基于神经网络的男子体质健康预测模型研究

利用人工神经网络强大的函数映射能力，以体质健康各评价指标测量成绩为输入参数、体质健康总分为输出参数，建立了体质健康神经网络预测模型。该模型克服了多元回归模型需要确定数学表达式的缺点，更准确地映射出各评价指标成绩与体质健康总分之间的函数关系,并随着新样本数据而不断更新。运用所建立的神经网络模型，绘制了各评价指标成绩与体质健康总分之间的相关曲线，为学生进行科学训练提供了理论依据。

Study on Prediction Model for Men Undergraduate's Constitution and Health Based on Artificial Neural Network

An Artificial Neural Network (ANN) model was developed to predict total score of constitution and health using the strong function mapping of ANN. In training of network , test results of five evaluation indexes were input variables , and total score was output variable . This model overcomes the shortcomings of multiple regression model, it can map the function relationship between test results of evaluation indexes and total score with high precision , and it can be updated continuously with new training datas . In this study , the relationship curve between each test index performance and final score is drawn using the trained ANN , and it offers theoretics foundation for Undergraduated's training scientifically.
