Application of classification tree in credit risk analysis 遞歸分類樹在信用風險分析中的應用
In this paper, we propose a modified minimize entropy principle approach ( mmepa ) and extract classification rule, and then build the classification tree model 在這里,提出一種基于mmepa(改進的最小熵原理方法)的決策樹構造方法,并通過一個實例對其進行說明,用此方法提取分類規(guī)則,構造決策樹模型。
This study employed six data mining methods, including logistic regression, discriminant analysis, artificial neural networks, k-nearest-neighbors, na ? ve bayes classifier, and classification trees, to find the most important factors of earthquake-caused landslide 本研究利用六種資料探勘方法,包括邏輯回歸、判別分析、類神經(jīng)網(wǎng)絡、最近鄰法、貝氏分類器、分類樹,探討影響地震引起山崩的重要因子。
To be dealed agaist extended data, this thesis has improved on and come true arithmetic of time sequence model, and amended conventional decision tree arithmetic, introduced the decision tree arithmetic for extended data, namely threshold value control approach . according to threshold value and concept hierarchy, threshold value control approach can set up the concise and statistic classification tree . at the same time, based on the theory of the concept lattice, this thesis introduces the arithmetic of mining association rules based on quantified concept lattice reduced by uncertainty coefficient 針對泛化后的數(shù)據(jù),本文改進并實現(xiàn)時間序列模式發(fā)現(xiàn)算法;修改了傳統(tǒng)的決策樹算法,提出了一種適合于泛化數(shù)據(jù)的決策樹構造算法:閾值控制法,閾值控制法通過閾值和概念層次的控制,可以建立簡潔明了、具有統(tǒng)計意義的分類樹;在概念格理論基礎上提出了基于不確定系數(shù)法挖掘關聯(lián)規(guī)則的算法。
This study uses classification tree to 1 . choose important variables for delivery launder, 2 . rank the importance of variables, and 3 . classify three levels of quantity of launder and examine under what conditions of variables for high level consuming class of laundry by analyzing the multiple response tables to provide a reference of marketing stratagem 本研究利用分類樹多變量統(tǒng)計探究技術做:一、篩選影響衣物外洗件數(shù)多寡之相關變數(shù),二、排序各個變數(shù)的重要性,三、將外洗量之多寡分成三個等級,由分析多變反應交叉表,可以得到每一個等級是在那些變數(shù)的那些條件下發(fā)生的,以供作洗衣業(yè)者對未來行銷策略規(guī)劃參考之依據(jù)。
