Title: Data science @ the new york times
Abstract: The Data Science group at The New York Times develops and deploys machine learning solutions to newsroom and business problems.
Re-framing real-world questions as machine learning tasks requires not only adapting and extending models and algorithms to new or special cases but also sufficient breadth to know the right method for the right challenge.
I'll first outline how
  • unsupervised,
  • supervised, and
  • reinforcement learning methods
are increasingly used in human applications for
  • description,
  • prediction, and
  • prescription,
I'll then focus on the 'prescriptive' cases, showing how methods from the reinforcement learning and causal inference literatures can be of direct impact in
  • engineering,
  • business, and
  • decision-making more generally.
Chris Wiggins is an associate professor of applied mathematics at Columbia University and the Chief Data Scientist at The New York Times. At Columbia he is a founding member of the   executive committee of the Data Science Institute, and of the Department of Applied Physics and Applied Mathematics as well as  the Department of Systems Biology, and is affiliated faculty in Statistics. He is a co-founder and co-organizer of hackNY (, a nonprofit which since 2010 has organized once a semester student hackathons and the hackNY Fellows Program, a structured summer internship at NYC startups. Prior to joining the faculty at Columbia he was a Courant Instructor at NYU (1998-2001) and earned his PhD at Princeton University (1993-1998) in theoretical physics. He is a Fellow of the American Physical Society   and is a recipient of Columbia's Avanessians Diversity Award. His forthcoming book "Data Science in Context: Foundations, Challenges, Opportunities", with Alfred Spector, Peter Norvig, and Jeannette M. Wing, will be published by Cambridge University Press in 2022 and is available in draft form online via His forthcoming book "How Data Happened: A History from the Age of Reason to the Age of Algorithms", with Matthew L. Jones, will be published by Norton Press in 2023.
