In addition, our algorithm mined more meaningful patterns considering not only the gain values of patterns but also different item importance by applying the weight factors into the erasable pattern mining framework. We also enhanced the mining performance of our algorithm by proposing a strong pattern pruning technique using the weight factor, and prevented unintended pattern losses caused by the weight factor through applying the overestimated method satisfying the anti-monotone property. The extensive performance evaluation results clearly supported the contributions of this paper. From the results and analyses of the performance evaluations, we determined that the proposed method is more efficient and scalable than the previous state-of-the-art approaches in terms of runtime, memory, and pattern generation aspects.
