Yes, you really can use this! - Applying Data Science to Real-World Problems

Thursday, March 2, 2017 - 5:00pm to 6:00pm
Schapiro Hall (CEPSR) Davis Auditorium
530 W 120th St.

Columbia Data Science Innovation Seminars

Ben Arancibia, Lead Data Scientist | Booz Allen Hamilton
Dan Liebermann, Lead Associate | Booz Allen Hamilton

Booz Allen Hamilton’s Dan Liebermann and Ben Arancibia will cover what it takes to get data science done in the real world. They will be sharing stories from the trenches – covering experiences and lessons learned from turning data science theory into reality when the problem (and the solution) are far from known. The talk will heavily engage the audience to hear their perspective, and cover the approach Booz Allen took to solve its clients’ problems. The goal is to get the audience thinking about what they would do in these situations and how they would apply their classroom experience.

Chief Scientist | Booz Allen Hamilton

The analytics community has invested significant resources in developing effective predictive analytical methods. However, even the most accurate predictive forecasts have limited value unless they can also provide clear action steps to bring about desired results.  In other words, the cause of the data is more important than the data itself.  Alex will introduce causal inference in the context of Bayesian Belief Networks (BBNs).  BBN’s produce accurate predictive forecasts, but with appropriate modeler input are also able to identify causal relationships between variables and pinpoint drivers of desired targets. With causal relationships identified, BBNs may be used in a prescriptive fashion in order to make actionable decisions.  Alex will dive into a case study in the aviation space which identifies causal drivers of daily flight operations on flight delays and allows us to prescribe delay-reduction plans by acting on controllable drivers.
