Title:
"Large Scale Automated Machine Learning for Digital Advertising:
Challenges and Opportunities"
Abstract:
Display advertising is maybe one of the most exciting playgrounds for applied research in data
analytics, machine learning, and predictive modeling. At Dstillery we observe daily about 10 Billion
user events representing the digital and geo-physical journeys of millions of people on desktops,
tablets and mobile phones. Our core analytical focus is finding good prospective customers for
marketers and serving them ads while preserving their privacy. In particular, we do not tag browsers
with any behavioral labels but instead work only with the set of hashed URL’s that the browser has
visited. This can be social media, user generated content, or Internet sites in general. A second core
component is bid optimization. Billions of online display advertising spots are purchased on a daily
basis through real time bidding exchanges (RTBs). Advertising companies bid for these spots on
behalf of a company or brand in order to purchase these spots to display banner advertisements.
These bidding decisions must be made in fractions of a second based on what location (Internet site)
has a spot available and who would see the advertisement. This talk will touch on a number of
challenges and analytical approaches to privacy preserving representations, robust high-dimensional
modeling, large-scale automated learning system, causal estimation from observational data, transfer
learning, and fraud detection.
Bio:
Claudia Perlich acts currently as Chief Scientist at Dsillery (previously m6d) and in this role designs,
develops, analyzes and optimizes the machine learning that drives digital advertising. She has
published over 50 scientific articles, and holds multiple patents in machine learning. She has won
many data mining competitions and best paper awards at KDD and is acting as General Chair for
KDD 2014. Prior to joining m6d in February 2010, Claudia worked in the Predictive Modeling
Group at IBM’s Watson Research Center, concentrating on data analytics and machine learning for
complex real-world domains and applications. Claudia holds a PhD in Information Systems from
NYU and continues to teach as an Adjunct Professor in the NYU Stern MBA program.
