Product Development Section: Promises and Risks of Emerging Data in Insurance

In the final episode of this mini-series, Shea and Anders cover the other common tree-based ensemble model, the Gradient Boosting Machine. Like Random Forests, GBMs make use of a large number of decision trees, but they use a “boosting” approach that cleverly makes use of “weak learners” to incrementally extract information from the data. After an explanation of how GBMs work, we compare them to Random Forests and go over a few examples where they have used GBMs in their own work.

Nichole Semprit, The Actuarial Foundation Senior Program Specialist and  Channy Cornejo, AP Calculus and AP Statistics Instructor at Santa Teresa High School discuss how the Foundation math competitions, Modeling the Future Challenge and The Hardest Math Problem Student Contest help students expand their skills, build confidence and win college scholarships.

Podcast on the industry adoption of emerging data sets across the insurance value chain. The participants include recognized leaders from business, regulation, legal, and innovation. The discussion covers current adoption practices, business opportunity, regulatory  and legal considerations.

Building on the discussion of individual decision trees in the prior episode, Shea and Anders shift to one of today’s most popular ensemble models, the Random Forest. At first glance, the algorithm may seem like a brute force approach of simply running hundreds or thousands of decision trees, but it leverages the concept of “bagging” to avoid overfitting and attempt to learn as much as possible from the entire data sets, not just a few key features. We close by covering strengths and weaknesses of this model and providing some real-life examples.

Dave Dillion and Bryon Robidoux discuss the book Dare to Lead, which was the Joint Risk Management and Leadership & Development Sections book club selection for December. They discuss what it means for managers to be vulnerable. How to give and receive feedback from both a manager’s perspective and the direct report perspective. The end the podcast talking about actuaries can be more curious and innovative.
