The 7 Most Important Data Mining Techniques Data

Data mining is the process of looking at large banks of information to generate new information. Intuitively, you might think that data mining refers to the extraction of new data, but this isnt the case; instead, data mining is about extrapolating patterns and new knowledge from the data youve already collected.
