A Model-Free Approach to Infer the Diffusion Network from Event Cascade

  title={A Model-Free Approach to Infer the Diffusion Network from Event Cascade},
  author={Yu Rong and Qiankun Zhu and Hong Cheng},
Information diffusion through various types of networks, such as social networks and media networks, is a very common phenomenon on the Internet nowadays. In many scenarios, we can track only the time when the information reaches a node. However, the source infecting this node is usually unobserved. Inferring the underlying diffusion network based on cascade data (observed sequence of infected nodes with timestamp) without additional information is an essential and challenging task in… CONTINUE READING
