Data preprocessing, a component of data preparation, describes any type of processing performed on raw data to prepare it for another data processing procedure. It has traditionally been an important preliminary step for data mining. More recently, data preprocessing techniques have been adapted for ...
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 is used in both database-driven and rules-based applications. In machine learning (ML) processes, data preprocessing is critical for ensuring large datasets are formatted in such a way that the data they contain can be interpreted and parsed bylearning algorithms.
