Data mining has been instrumental in the extraction of some useful knowledge from data. The purpose of data mining has always been to focus on searching for methods to extract instead of revealing the implicit models of the data. The outcome of the process of data mining is the knowledge that is represented by different visualization techniques. Knowledge obtained through data mining is not effective without the interventio Read More
