Discuss the strengths and weaknesses of both methods.
C4.5rules is an implementation of an indirect method for generating rules
from a decision tree. RIPPER is an implementation of a direct method for
generating rules directly from data.
The C4.5 rules algorithm generates classification rules from a global
perspective. This is because the rules are derived from decision trees,
which are induced with the objective of partitioning the feature space
into homogeneous regions, without focusing on any classes. In contrast,
RIPPER generates rules one-class-at-a-time. Thus, it is more biased
towards the classes that are generated first.
