Continuous Attributes
Many data mining algorithms including the TDIDT tree generation algorithm require all attributes to take categorical values However in the real world |
Examples of data attributes include numerical values (e.g., age, height), categorical labels (e.g., color, type), textual descriptions (e.g., name, description), or any other measurable or qualitative aspect of the data objects.11 fév. 2024
What is an example of a discrete attribute?
A discrete attribute has a finite or countably infinite set of values, which may or may not be represented as integers.
The attributes hair_color, smoker, medical_test, and drink_size each have a finite number of values, and so are discrete.
