Discovering utility-based episode rules in complex event sequences
Our work is the first one that aims at mining high utility-based episode rules. We propose an efficient algorithm UBER-Mine for mining high-utility episode rules. A compact tree structure is proposed to reduce search space in the mining process. Experimental results show that our proposed algorithms have good scalability. Our method can be used for real-world applications including stock investment.
