机器学习和数据挖掘有什么联系又有什么区别？

现在machine learning and data mining貌似很火的,他们之间有何区别，又有什么联系？有那位大神可以说得详细点（ps:我觉得大多帖子说得都挺模糊的),另外和统计的关联大吗？

Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD),[1] an interdisciplinary subfield of computer science,[2][3][4] is the computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.[2]
