Categorical data

  • 2024-10-21 (modified: 2024-10-22)

Features having a specific set of possible values. For example, consider a categorical feature named traffic-light-state, which can only have one of the following three possible values:

  • red
  • yellow
  • green

By representing traffic-light-state as a categorical feature, a model can learn the differing impacts of red, green, and yellow on driver behavior.
