2020 Webinar - Ensembles and Combining Models - January 9
Ensembles are powerful analytical methods used commonly in the wider Predictive Analytics community outside of Insurance. We’ll describe the rationale and explain the effectiveness of ensembles in general, as well as the basic approaches of bagging and boosting for ensembles of trees. Advantages of ensembles on insurance data will be shown and the issues surrounding complex models discussed. Finally, strategies for combining linear regression and ensemble models will be explored through a case study.
