tree well meaning in Chinese
树坑
Examples
- There was no undergrowth, only the smooth grass, very green and fresh, and the big gray trees well spaced as though it were a park .
没有灌木，只有青翠欲滴的、平坦的草地、灰色的参天大树之间的间距井井有条，宛如一座公园。 - By analyzing expression between a and fuzzy entropy from the view of analytics , this paper analyses the relationship of between a and fuzzy entropy and the changing trend of fuzzy entropy function with the increase of a , then discusses the sensitivity of the parameter a to classification result such as total nodes , rule number , classification accuracy of fuzzy decision tree , proposes an experimental method of obtaining optimal a , it is proved by experiment that the optimal value a obtained by this method can make the classification result of fuzzy decision tree best , and therefore provides the academic evidence of selecting parameter a in order to gain the best classification result
本文在visualc + +软件开发平台及模糊id3算法的基础上，从解析的角度出发，通过分析参数与模糊熵之间的函数关系式，讨论了随着的增加，模糊熵函数的变化趋势，进一步分析了参数对模糊决策树的分类结果在训练准确率、测试准确率、规则数等方面所表现出的敏感性，探讨了得到最优参数的实验方法。实验证明，利用这一方法得到的最优参数的值，可以使模糊决策树的分类结果达到最好的效果，从而为人们用模糊决策树进行分类时选取参数以获得最优的分类结果，提供了良好的理论依据。 - A new heuristic search method is devised for maximum likelihood method , which first constructs a starting tree , and then through branch swapping searches for trees best resembling the present optimal tree and locates a better tree . repeat this process , till no more better trees are generated or the upper iteration limit is arrived and the program ends
对最大似然法,改进了一种新的启发式搜索:随机建立一棵初始树,然后通过查看与当前最优树拓扑最近的树,从中寻找更优树,不断地更新当前最优树,直到无法找到更优树或者达到了搜索次数的上限,算法停止。
