Mining of Temporal Optimal High Utility Item Sets from Data Streams
Temporal High Utility Item (THUI) mining has become an emerging research topic in the data mining field, and finding frequent item sets is an important task in data mining with wide applications. Two basic factors to be considered in utility mining. First, the utility (e.g., profitability, time) of each item may be different in real applications; second, the frequent item sets might not produce the highest utility. In this paper, the authors propose a novel algorithm named TOUIG (Temporal Optimal Utility Item set Generation) which can find optimal high utility item sets from database.
