Data Mining Evaluation "Selection" is the step where we identify the data, "preprocessing" is where we cleanse and profile the data, "transformation" step is required for data preparation, and then is data mining. Lastly we use "Evaluation" to test the result of the data mining.

Data mining is the process of extracting patterns from large data sets by connecting methods from statistics and artificial intelligence with database management. Although a relatively young and interdisciplinary field of computer science, data mining involves analysis of large masses of data and conversion into useful information.

By far, the most famous dimension reduction approach is principal component regression.. Principal Component Analysis (PCA) is a feature extraction methods that use orthogonal linear projections to capture the underlying variance of the data.. PCA can be viewed as a special scoring method under the SVD produces projections that are scaled with the data variance.

Although the volume of data has been reduced, we are still asking the user to find a needle in a haystack. Requiring rules to have a high minimum support level and a high confidence level risks missing any exploitable result we might have found. One partial solution to this problem is differential market basket analysis, as described below.
