The decision tree had a lot of algorithms , this paper focus on the optimization of fast classification in the face of n - value attribute of id3 algorithm which had parameters of user ' s interest . on the basis of avoiding the weak relevant attribute of n - value covered the worth strong relevant attribute , simplify complexity of the original algorithm and code cost through the mathematics tool , thus raise the speed of operation while using this algorithm , and lower costs in thrift as much as possible , to raise the efficiency 決策樹(shù)學(xué)習(xí)有很多算法,本文著重研究了對(duì)引入用戶興趣度參數(shù)的id3算法在面對(duì)多值屬性時(shí)的快速分類的優(yōu)化,在避免了多值弱相關(guān)屬性覆蓋少值強(qiáng)相關(guān)屬性的基礎(chǔ)上,通過(guò)數(shù)學(xué)工具簡(jiǎn)化原算法的復(fù)雜度和編碼代價(jià),從而提高使用該算法時(shí)的運(yùn)算速度,盡量多的節(jié)約計(jì)算時(shí)間,從而達(dá)到降低成本的,提高效率的目的。
