Unsupervised Streaming Feature Selection in Social Media
The explosive and viral nature of social media creates massive amounts of high-dimensional data. Features such as hashtags, keywords, or slang words are created every day and quickly become popular within a short period of time. However, social media data is not fully structured and its features are usually not predefined. One way to resolve this problem...

Residual Analysis for Anomaly Detection in Attributed Networks
Background Attributed networks are networks whose nodes contain rich sets of features or attributes. In social networks, for instance, attributes may be user interests, while for paper citation networks they may be papers associated with an institution or scholar. The pervasiveness of attributed networks across numerous domains has given rise to the...
