I would be really impressed if someone with an actuarial science degree has any experience with machine learning. That is not a skill that is taught outside of self learning or an absolute need. It may be more applicable in a property casualty company where there are things like telematics.
The society of actuaries is now testing basic analytics and R programming as part of the exam system. The Introduction to statistical learning book is on the exam syllabus.
You are correct, and I view it as an attempt to remain relevant in an area they feel threatened by. We will see what the exam ends up being like, but I have little faith in the SOA being able successful test someone’s experience in “predictive analytics” with a five hour proctored exam.
