A Study of Decision Tree Classifier
-
摘要: 本文从理论上给出了树分类器的数学定义,探讨了分类树的优化和性能评价函数这两个 关键问题.从而提出了在卫星多光谱数据分类中切实可行的优化树分类器设计方法,包括合 理的性能评价函数、新型的分类树数据结构和搜索的优化算法.最后给出了应用于森林分类 的实验结果.Abstract: In this paper,a mathematical delinition of decision tree classifier is given. Two key problems --optimization of the decision tree classifier and performance measure are studied, so that an approach to the design of decision tree classifier with application to satellite multispectral data classification is proposed, including reasonable performance measure, a special data structure, and optimization algorithm for searching. Finally, experimental results of forest classification is also given.
