Data mining: an industrial research perspective

摘要: Just what exactly is data mining? At a broad level, it the process by which accurate and previously unknown information extracted from large volumes of data. This should be in form that can understood, acted upon, used for improving decision processes. Obviously, with this definition, mining encompasses set technologies, including warehousing, database management, analysis algorithms, visualization. The crux appeal new technology lies since they provide automated mechanisms sifting through extracting useful information. capability these coupled today's warehousing management technology, make corporate industrial possible. representation model such algorithms quite straightforward. Data considered to collection records, where each record fields. Using tabular model, are designed operate on contents, under differing assumptions, delivering results formats. (or as more popularly known nowadays) divided into three major categories based nature their extraction: predictive modeling (also called classification or supervised learning), clustering segmentation unsupervised frequent pattern extraction.
