Short Description:
Our world is networked: people are closer to each other through online social network services or mobile communication networks, while information is capable to be exchanged faster by World Wide Web or email networks. The social network is a treasure trove of user experiences and knowledge that presents great opportunities to understand the fundamental science of our world. In turn, many prediction tasks on nodes and edges have attracted considerable attention from both industry and academia. However, these tasks require careful effort in engineering features used by learning algorithms. While social network features require high computational resources and hard domain knowledge, it is critical to address the problem of learning network features automatically. Recent research in the broader field of network embedding, also known as representation learning for networks, has led to significant progress in automating prediction by learning the features themselves. The goal of network embedding is to project a network into a low-dimensional space, where each node can be presented as a single point in the learned latent space. However, many social network properties can not be captured by general network embedding algorithms. For instance, social networks are dynamic over time, while in most cases they are scale-free. This session aims to provide a forum for presenting the most recent advances in representation learning for social networks. We expect novel research on either frontier algorithms and models, or novel applications of network embedding on link prediction, fraud detection, network analysis, user modeling, and so on.
