智能一卡通的公交车已极大地方便了人们的出行,最近研究人员又在开发它的新功能:抓小偷!在北京完成测试的这种公交车,采取大数据挖掘方法,已成功地“验证”了近93%的小偷。美国罗格斯大学熊辉教授等人日前在旧金山举行的知识发现和数据挖掘大会上报告了这一成果。其原理如下:绝大多数乘客乘坐公交车或地铁出行时,会选择最优出行方案,要么用时最短,要么换乘次数最少;但有极少 Smart card bus has greatly facilitated people's travel, and recently researchers are also developing its new features: to grasp the thief! This bus to be completed in Beijing to take a big data mining method has been successfully Nearly 93% of the thieves. Prof. Xiong Hui, from Rutgers University in the United States, reported on this achievement recently at the Knowledge Discovery and Data Mining Conference in San Francisco. The principle is as follows: The vast majority of passengers travel by bus or subway, will choose the best travel options, either use the shortest time, or the least transfer times; but there are very few
