摘要
机器学习技术在现代各种数据分析中是备受关注的有效方法之一,目前已在众多领域得到广泛应用。文章以目前较为流行的决策树学习为重点,介绍了决策树学习的几个较为成熟的算法,并将相应算法应用到机械波图像分析中,提出了5点、7点与11点上下文决策树学习算法。通过实验验证该处理方法是有效的。
Machine learning technique is an effective way of modern data analysis. It has been widely used in many fields and got a lot of attention. Focusing on the most popular decision tree learning, a few of the most sophisticated algorithms are introduced. Then the corresponding algorithm is applied to the image analysis of the mechanical wave, and the five-point, seven-point and eleven-point context- based decision tree learning algorithms are proposed. The approach is proved to be meaningful by ex- perimental validation.
