Systems and Algorithms for Few-Shot Node Classification on Graphs
­Node classification in real-world attributed networks is a central analytical task that is a growing research area. In real-world networks, a large portion of node classes only contain limited labeled instances. Many prevailing graph machine learning methods typically rely upon the availability of sufficient labeled data. However, the long-tail...

Exploring Personal Attributes from Publicly Available Interactions to Secure Users’ Privacy
As social networking becomes more popular, sensitive personal information seems to become much more readily available on the web. Although some social networks have privacy settings the user can change, some user-created data is simply unchangeable, and thus, remains public. Websites inadvertently store information such as links clicked on, liked, favorited,...

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...
