Incremental Mining of High Utility Patterns in One Phase by Absence and Legacy-Based Pruning
Mining high utility patterns in dynamic databases is an important data mining task. While a naive approach is to mine a newly updated database in its entirety, the state-of-the-art mining algorithms all take an incremental approach. However, the existing
