Data preprocessing, a component ofdata preparation, describes any type of processing performed on raw data to prepare it for anotherdata processingprocedure. It has traditionally been an important preliminary step fordata mining. More recently, data preprocessing techniques have been adapted for training...
Thanks to data preprocessing, it is possible to convert the impossible into possible, adapting the data to fulfill the input demands of each data mining algorithm. Data preprocessing includes the data reduction techniques, which aim at reducing the complexity of the data, detecting or removing ...
