Wonyeol Lee (CSE 10, advisor Professor Hwanjo Yu) won the Student Travel Award from 2012 IEEE International Conference on Data Mining (ICDM) by his paper, “CT-IC: Continuously activated and Time-restricted Independent Cascade Model for Viral Marketing.” ICDM is a conference at which papers on field of data mining are presented. The Student Travel Award was started to encourage students to submit papers to the conference.
The subject of Lee’s paper is influence maximization problem. When any social network and the number of selected people are provided, selecting a certain number of people that can maximize influence spread is the problem. To solve this problem, an influence diffusion model is required but existing models are based on impossible suppositions. Accordingly, Lee suggests a more realistic influence-diffusion model and proposes a new algorithm that can solve the influence maximization problem. This problem can be adjusted in real world situations, such as viral marketing.
