Data mining is the process of using advanced software, algorithms, and statistical techniques to analyze large volumes of data in order to uncover hidden patterns, relationships, and trends. By sifting through vast datasets, data mining enables businesses and organizations to extract valuable insights ...
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...
