Research Abstract

I proposed a mathematical model named IDM that represents an influence diffusion process on the Internet and investigated the validity of the model by analyzing the various data. Based on the theoretical analysis of the IDM, I also improved the IDM to be more reliable for the biased data. Also, I proposed a computationally less intensive IDM to be able to apply to big data.
