为了使学生更好地理解和掌握留一法交叉验证的计算过程,在实验教学中利用Excel分步完成留一法交叉验证的计算过程。这不仅实现了教学内容与计算机软件应用的有机融合,而且细化了计算方法,有利于学生的学习和掌握,达到了激发学生学习兴趣,提高实验教学质量的效果。
Making students understand and master the calculation process of leave- one – out cross validation better,in experimental teaching,using Excel to finish the counting process of leave- one – out cross validation step by step. In this way,it does not only integrate teaching contents with computer software together,but also refine the calculation method. It is good for studying and mastering.It aims to motivate students,interests,and improve the efficiency of experimental teaching quality
