本文在visualc + +軟件開發(fā)平臺及模糊id3算法的基礎(chǔ)上，從解析的角度出發(fā)，通過分析參數(shù)與模糊熵之間的函數(shù)關(guān)系式，討論了隨著的增加，模糊熵函數(shù)的變化趨勢，進(jìn)一步分析了參數(shù)對模糊決策樹的分類結(jié)果在訓(xùn)練準(zhǔn)確率、測試準(zhǔn)確率、規(guī)則數(shù)等方面所表現(xiàn)出的敏感性，探討了得到最優(yōu)參數(shù)的實(shí)驗(yàn)方法。實(shí)驗(yàn)證明，利用這一方法得到的最優(yōu)參數(shù)的值，可以使模糊決策樹的分類結(jié)果達(dá)到最好的效果，從而為人們用模糊決策樹進(jìn)行分類時選取參數(shù)以獲得最優(yōu)的分類結(jié)果，提供了良好的理論依據(jù)。 - 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(jìn)了一種新的啟發(fā)式搜索:隨機(jī)建立一棵初始樹,然后通過查看與當(dāng)前最優(yōu)樹拓?fù)渥罱臉?從中尋找更優(yōu)樹,不斷地更新當(dāng)前最優(yōu)樹,直到無法找到更優(yōu)樹或者達(dá)到了搜索次數(shù)的上限,算法停止。 - It's difficult to find tree well in a sentence. 用tree well造句挺難的
