Data Attributes in Data mining
Attributes in data mining play a crucial role in representing the characteristics and properties of data objects within a dataset. They serve as the foundation for data analysis, modeling, and knowledge discovery. Attributes can take on various types, each defining the nature and format of the data they represent. Understanding these attribute types is essential for successful data mining and extracting valuable insights. Let’s explore 30 common types of attributes along with their real-life examples:
