Hi @davidlkl,
I work as an actuarial consultant at EY Spain. We do not normally participate in pricing projects. However, it is a topic that interests me personally and that is why I have participated in this competition.
I can tell you that Spanish insurers still mostly use GLMs. However, there are several large insurers that have started to introduce machine learning techniques for pricing. As well as in other aspects such as fraud detection.
With what I estimate that in 3 or 4 years the active use of all these models from an explainable machine learning perspective, in order to justify their use to the different national supervisory authorities.
Regards,
