Rule-based classification of player types in computer games and rule-based classification

Compared to other classification algorithms, the learned model for a rule-based classification is set up by an IF-THEN rules set. The rules set can be transformed from the decision tree or by the following algorithm. An IF-THEN rule has the following format:

          IF condition_holds_true THEN make_a_conclusion

An alternative format is as follows:

For a given instance or record in the source dataset, if the RULE antecedent holds true, the rule is defined to cover the instance, and it is satisfied.

Given a rule R, the coverage and accuracy are defined as follows:
