Learning with peers helps students reflect, generalize knowledge and apply it more successfully to new problems. How can we scale successful peer learning from the controlled environment of the small classroom to the wild, massive scale of online classes?

The talk will survey a number of open problems in computer security, and discuss recent progress on communication systems that hide the metadata. We will present a recent system, called Riposte, that uses cryptographic techniques to provide anonymous Tweets for very large anonymity sets.&nb
An Infovore is an information-based entity that explores the world, learns, and applies these learnings effectively. In essence: a form of weak AI. We have been working on a general-purpose infovore for making decisions using elements of contextual bandits, systems, and experts-style

In order to create truly autonomous physical robots, understand the underlying principles behind human movement, or tell narratives in animated films and interactive games, it is necessary to synthesize movement behaviours with the same wide variety, richness and complexity observed in humans and
Humans as well as information are organized in networks. Interacting with these networks is part of our daily lives: we talk to friends in our social network; we find information by navigating the Web; and we form opinions by listening to others and to the media.
