Practical Applications of Data Mining

dataset should be used instead of the entire dataset to reduce the time needed

for data mining. The training dataset is obtained during pre-processing, and

it often contains useful information for data analysis. This dataset can also be

used by the data-mining algorithms as a model of the raw data.

Once a certain amount of knowledge is generated by the data-mining

stage, the generated pieces of knowledge have to be converted into a form

more suitable for interpretation by end users in a post-processing stage. The

main purpose of post-processing is to synthesize the generated knowledge

into useful and usable information for strategic decision making by end

users. During the post-processing stage,
