The data preprocessing is one of important steps in data mining, we won't get such high level result of data mining unless we have pretreated the data into an easy-to-go one. The data preprocessing can define as the operations as followings: data cleaning, data integration, data conversion, data reduction.

Data preprocessing in data mining involves operations like data cleaning, integration, conversion, and reduction, which are crucial for achieving high-quality results in data mining.
