A general observation on the dataset with regards to
accuracy is the dimensionality of the class attribute. This
means, the smaller the dimension or attribute values for the
class variable; the higher the accuracy of the model. This was
observed from the ‘classified’ and the ‘clustered’ dataset. The
classified dataset has a class with four attribute values (i.e acc,
unacc, good, vgood), thus; having a model with the highest
accuracy to be 93%. This accuracy is low compared to the
clustered car dataset which has only two clusters (i.e. cluster1,
and cluster2) as values for the class attribute, and the accuracy
obtained from using the clustered dataset to build a model was
100% across all algorithms used under different experiment
settings
