【摘要】：提出了基于相似度的離群模式發(fā)現(xiàn)模型 ,該模型主要利用知識(shí)屬性集分析離群點(diǎn) ,既能夠處理離群點(diǎn)的數(shù)值屬性 ,又能夠處理其類別屬性 ;通過(guò)組間相似度從中發(fā)現(xiàn)離群模式 ,不僅回避離群點(diǎn)數(shù)量少的缺陷 ,還利用了離群點(diǎn)的隱含語(yǔ)義 .給出了在銀行結(jié)售匯交易數(shù)據(jù)上進(jìn)行的實(shí)驗(yàn)分析結(jié)果 ,模型發(fā)現(xiàn)了某地區(qū)的 3個(gè)可疑模式 ,該結(jié)果為金融犯罪分析提供有利線索 ;利用不同子空間角色劃分 ,可以發(fā)現(xiàn)個(gè)人、地區(qū)等不同對(duì)象間的異常資金流動(dòng) ;模式發(fā)現(xiàn)算法具有線性時(shí)間復(fù)雜度 ,在實(shí)際應(yīng)用中具有較好的性能 .結(jié)果表明模型能檢測(cè)出可疑資金流動(dòng)序列 ,為反洗錢工作提供有意義的線索 .
[Abstract]:An outlier pattern discovery model based on similarity is proposed. The model is mainly used to analyze the outliers by using the knowledge attribute set, which can not only deal with the numerical properties of the outliers, but also can handle the class attributes of the outliers, and find the outliers through the similarity among the groups. It not only avoids the defects of the number of outliers, but also uses the hidden semantics of the outliers. The result of the experimental analysis on the transaction data of the bank settlement is given. The model has found three suspicious patterns in a certain area. The result provides an advantageous clue for the analysis of the financial crime, and can find the individual by using the different sub-space characters. The pattern discovery algorithm has a linear time complexity and has better performance in practical application. The results show that the model can detect the flow sequence of suspicious funds and provide meaningful clues to the work of anti-money laundering.
