Simons Foundation Lectures are free public colloquia related to basic science and mathematics. These high-level talks are intended for professors, students, postdocs and business professionals, but interested people from the metropolitan area are welcome as well.
In this talk, David Blei will review the basics of topic modeling and describe his recent research on collaborative topic models—models that simultaneously analyze documents and the corresponding reader behavior. Blei will explain how using collaborative topic models to discover patterns in how people read can help point readers to relevant new documents. Finally, he will discuss the broader field of probabilistic modeling, which gives data scientists both a rich language for expressing statistical assumptions and scalable algorithms for using those assumptions to uncover hidden patterns in massive data.
