Fake Profile Identification

Millions of us post on Facebook, send a tweet, or upload photos on online social networks. But how safe is the information we share?

Recent reports indicate that networks like Facebook and Twitter are infested with tens of millions of fake user profiles. Fake users on online social networks can jeopardize your safety both in the online world and in the real world. Our research team has created a set of machine-learning based solutions to identify fake users.

Computational Genealogy

Genealogical research is a popular hobby. Many people pour over sources such as birth and death certificates, wills, letters, and land deeds to assemble their family trees. A lot of these get uploaded and shared in online projects such as WikiTree, which creates vast datasets of interconnected family trees. Machine learning techniques can analyze such data, and the results show patterns in population gender ratios, marriage trends, fertility, lifespans, and the frequency of twins and triplets.
