本文以新疆伊犁500位13~17岁青少年男子50米短跑及相关体质项目测试数据为基础
建立随机森林模型进行估计精度分析及变量评估的研究
发现随机森林模型对于复杂数据有较好的适应性和较高拟合效果
根据青少年短跑成绩影响因素研究
为非专业青少年短跑训练提供建议.
This paper takes the Xinjiang Yili region 500 teens aged 13 to 17 men's 50 m sprint and related physical project based on the test data
a random forest model estimation precision analysis and evaluate the variables
found that the random forest model for complex data has good adaptability and high fitting effect
according to the research to the influential factors of teenage sprinters
provide suggestions for non-professional teenagers sprint training.
