Title: Adventures in Crowdsourcing

Abstract: Crowdsourcing is becoming increasingly popular in many fields. In this talk, I will describe a set of systems that we built over the last few years, which combine human and machine intelligence, to create systems that are better than using humans or computers alone.  I will cover a diverse set of topics surrounding the creation of such systems, including worker quality control, fair payment schemes, vulnerability detection for machine learning systems, and how to use online advertising systems for targeting  knowledgeable users. Time permitting, I will conclude with an illustration of how Mechanical Turk workers and mice are not that different after all.
