Description: A derived attribute is a feature created from existing data to enhance the dataset. In the field of data science, these attributes are fundamental for enriching data analysis and modeling. By deriving new attributes, patterns and relationships that are not evident in the original data can be captured. For example, from a date of birth, one can derive a person’s age, which may be more useful for certain analyses. Derived attributes can be numerical, categorical, or even temporal, depending on the nature of the source data and the analysis objective. The creation of these attributes involves data transformation techniques, such as normalization, discretization, or combining multiple variables. In summary, derived attributes are powerful tools that allow data scientists to improve the quality of their models and gain deeper insights from the available data.
