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 + +軟件開發平臺及模糊id3算法的基礎上,從解析的角度出發,通過分析參數與模糊熵之間的函數關系式,討論了隨著的增加,模糊熵函數的變化趨勢,進一步分析了參數對模糊決策樹的分類結果在訓練準確率、測試準確率、規則數等方面所表現出的敏感性,探討了得到最優參數的實驗方法。實驗證明,利用這一方法得到的最優參數的值,可以使模糊決策樹的分類結果達到最好的效果,從而為人們用模糊決策樹進行分類時選取參數以獲得最優的分類結果,提供了良好的理論依據。
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 對最大似然法,改進了一種新的啟發式搜索:隨機建立一棵初始樹,然后通過查看與當前最優樹拓撲最近的樹,從中尋找更優樹,不斷地更新當前最優樹,直到無法找到更優樹或者達到了搜索次數的上限,算法停止。
百科解釋
A tree well is a void or area of loose snow around the trunk of a tree enveloped in deep snow. Also known as "spruce traps", these voids present danger to hikers, snowshoers, skiers, and snowboarders who fall into them.
