The Definition of Data Mining 資料探勘是利用人智慧、機器學習、統計分析或資料庫系統由大量資料中發掘出特定的類型。瞭解資料的特徵與關係可以提供決策時所需要的資訊，並做出預測。 Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD), an interdisciplinary subfield of computer science, 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. The overall goal of the data mining process is to extract information from a data set and transform it into an understandable structure for further use. (Wikipedia, 2013)
