Data Set Information:
Car Evaluation Database was derived from a simple hierarchical decision model originally developed for the demonstration of DEX, M. Bohanec, V. Rajkovic: Expert system for decision making. Sistemica 1(1), pp. 145-157, 1990.)
The model evaluates cars according to the following concept structure:
Car Evaluation is based on parameters
- PRICE overall price
- maint price of the maintenance
- TECH technical characteristics
- COMFORT comfort
- Doors number of doors
- persons capacity in terms of persons to carry
- lug_boot the size of luggage boot
- safety estimated safety of the car
Attributes:
- buying: vhigh, high, med, low.
- maint: vhigh, high, med, low.
- doors: 2, 3, 4, 5more.
- persons: 2, 4, more.
- lug_boot: small, med, big.
- safety: low, med, high.
To predict the car evaluation I have used adaboost classifer which have given 93% accuracy.
