Car Evaluation Database :
The car evaluation database is derived from a simple hierarchical decision-making model initially developed to represent expert decision-making systems. Characteristics include purchase price, maintenance costs, number of doors, number of passengers it can carry, size of the luggage compartment, and estimated vehicle safety. The target class is unacceptable, acceptable, good, and very good.
