A process that occurs after training that removes similar association rules that exist in a parent-child relationship. If the child meets three criteria, the system will remove it. The criteria are: 1) the child must match the parent; 2) the child (for example, [San Jose, Finance]) is a superset of the parent rule (for example, [Finance]); 3) the child and parent’s confidence scores are within a +/- range of each other. The range is set in the configuration file.
