A representation-learning approach for insurance pricing with images

Christopher Blier-Wong, Luc Lamontagne, Etienne Marceau

Unstructured data are a promising new source of information that insurance companies may use to understand their risk portfolio better and improve the customer experience. However,…

A new method to construct high-dimensional copulas with Bernoulli and Coxian-2 distributions

Christopher Blier-Wong, Hélène Cossette, Sébastien Legros +1

We propose an approach to construct a new family of generalized Farlie-Gumbel-Morgenstern (GFGM) copulas that naturally scales to high dimensions. A GFGM copula can model moderate…

Collective risk models with FGM dependence

Christopher Blier-Wong, Hélène Cossette, Etienne Marceau

We study copula-based collective risk models when the dependence structure is defined by a Farlie-Gumbel-Morgenstern (FGM) copula. By leveraging a one-to-one correspondence between…

Efficient evaluation of risk allocations

Christopher Blier-Wong, Hélène Cossette, Etienne Marceau

Expectations of marginals conditional on the total risk of a portfolio are crucial in risk-sharing and allocation. However, computing these conditional expectations may be challeng…

Exchangeable FGM copulas

Christopher Blier-Wong, Hélène Cossette, Etienne Marceau

Copulas are a powerful tool to model dependence between the components of a random vector. One well-known class of copulas when working in two dimensions is the Farlie-GumbelMorgen…

Geographic ratemaking with spatial embeddings

Christopher Blier-Wong, Hélène Cossette, Luc Lamontagne +1

Spatial data is a rich source of information for actuarial applications: knowledge of a risk's location could improve an insurance company's ratemaking, reserving or risk managemen…
