Abstract:
This presentation is based on a recent actuarial paper published in Astin Bulletin, introducing a novel network called KAN (Kolmogorov-Arnold Network) and its application in mortality modeling. KAN is a recently emerged network over the past year or two. Building upon conventional neural networks and their latest extension, CANN (Combined Actuarial Neural Net), the presentation systematically introduces the application of KANN in mortality modeling and compares it with various existing methods. The findings demonstrate that both KAN and KANN offer advantages over existing approaches in terms of model interpretability and smoothness of fitted curves.
