| 摘 要： | 介绍了一种基于余弦相似度模型的最佳教练遴选算法.该方法首先定义了执教能力评价指标，并针对指标中的时间相关因素给出了修正方法，最大程度地削减了时间因素对教练遴选算法的影响.采用单因素方差分析方法分析了性别对排名结果的影响，在此基础上提出了基于白化方法的改进策略，消除了性别的影响.采用对比策略，将所有教练的评价指标向量与理想化教练向量之间进行余弦相似度计算，最终遴选出最佳教练.基于实际数据的实验结果验证了算法的有效性.

| Abstract: | A similarity calculation method was applied to establish the mathematical model to select the best coach. The index vector was defined to assess the coaching ability of coacher. The improved method was given to reduce the impact caused by the factor of time. The variance analysis was used to assess the impact caused by the gender. Based on this analysis，the whitening approach was used to remove the impact caused by the gender. To apply cosine similarity to select the best coach， criteria collected based on experience should be transferred as vectors， then compared with the idealistic coach. Many experiment results demonstrated the validity of the proposed method. |
