%description
Provides implementations of a classifier based on the "Classification
Based on Associations" (CBA). It can be used for building classification
models from association rules. Rules are pruned in the order of precedence
given by the sort criteria and a default rule is added. The final
classifier labels provided instances. CBA was originally proposed by Liu,
B. Hsu, W. and Ma, Y. Integrating Classification and Association Rule
Mining. Proceedings KDD-98, New York, 27-31 August. AAAI. pp80-86 (1998,
ISBN:1-57735-070-7).
