提起数据挖掘,你马上会条件反射般想到“啤酒和尿布”?20年前,沃尔玛通过对一年多的原始交易数据进行分析,发现啤酒和尿布的销量具有一定的正相关,原来美国的妈妈们经常嘱咐她们的丈夫下班以后为孩子买尿布,而丈夫在买完尿布之后顺手买回自己爱喝的啤酒……别傻了,这是商学院流传出的教材案例,真假莫辩,更何况沃尔玛自己从来没有正式承认过他们通过数据挖掘和分析发现了年轻爸爸们的“顺手购”习惯。 Twenty years ago, Wal-Mart analyzed the raw transaction data over a year ago and found that sales of beer and diapers had some positive correlation. Originally, the United States Often ask their husbands to buy diapers for their children after get off work, while her husband buys his favorite beer after buying diapers ... Do not be stupid, this is a case of teaching materials circulated by business schools. , Not to mention that Wal-Mart has never formally acknowledged that they found the “easy shopping” habits of young dads through data mining and analysis.
