The ubiquitous use of mobile devices, combined with the emergence of cloud-based computing and storage infrastructure, has made it possible to trace every facet of human life. This data, when analyzed carefully, presents an unprecedented opportunity to learn about ourselves; how we behave, what we need, and what we love. The success of many online services, such as Facebook, Pandora, and Amazon, demonstrates how this data can be used to provide valuable services that users love. In this talk, I will explain a class of enormously successful learning models, probabilistic topic models, that have been used to learn about users and categorize their data for many online services.
