Without data mining utilities, handling with regression models is the bottleneck of the whole job. This paper introduces a practical method of constructing real estate price indices, using the most common database software Microsoft SQL Server 2005, and gives out a demonstration. The result shows ...
3 关联规则(Association) 关联规则是另一类常用的数据挖掘任务。关联规则也被称作购物篮分析。一个典型的基于关联规则的数据挖掘任务是,通过对销售事务表的分析,得出经常出现在同一个购物篮中的商品有哪些。从一般化角度来说,关联规则通常用于识别一些经常出现的商品集合和规则,其识别结果将用于指导交叉销售。 对关联规...
很多人误以为 Data Mining(数据挖掘)只是“写 SQL 跑分析”,其实它远比这复杂也更强大。 Data Mining是: 在大量结构化或非结构化数据中, 通过算法和建模, 识别出隐藏的模式、趋势、异常、分类与关联, 为业务决策、风险预警、机会识别提供深度洞察。 它不是事后分析,而是让数据主动揭示未知。 一个常见混淆在于将...

The Mass Query Language (MassQL) enables scientists to precisely express and reproducibly search for mass spectrometry (MS) peak patterns in large MS datasets. MassQL has been adopted across the most popular open source and commercial MS analysis platforms and has demonstrated how mining MS data ...
