Les apports de l’open data pour les assureurs
White paper
La capacité à accéder à de nouvelles sources de données offre de nombreuses perspectives concernant la gestion des risques des assureurs. Alors que les Insurtechs transforment le marché de l’assurance, tant sur le plan des services et de l’expérience utilisateur que de la création de produits innovants, les assureurs traditionnels misent également sur la donnée pour enrichir leur activité et la connaissance de leurs risques.

Sécheresse 2022 – Analyse du risque subsidence en France
White paper
D’après l’étude Impact du changement climatique sur l’assurance à l’horizon 2050 produite par FA (France Assureurs), le coût des sinistres climatiques devrait doubler sur la période 2020-2050. Ce document est une synthèse des analyses produites par Milliman en utilisant différentes sources de données (notamment : les arrêtés CatNat de la CCR, les données ERA5 de l’ECMWF, le bilan climatique du printemps 2022 de Météo France, les données RGA de la BRGM et de l’ESDAC et ADMIN-EXPRESS de l’IGN).

Potential data sources for life insurance AI modelling
White paper
Every day, more than 2.5 quintillion bytes of data are created, and that pace is only accelerating. Big data, combined with the increased usage of machine learning algorithms, allows the life insurance industry to model the surrounding world much more effectively than in the past. Insurers can better understand underwriting risks, improve customer service, and lower costs. Better data can also improve the health of customers. In this report, we explore in detail what kind of data can be used to…

The use of artificial intelligence and data analytics in life insurance
White Paper
This research paper first presents the technical foundations and key principles of data analytics techniques, then outlines use cases that have been developed by life insurers, reinsurers and insurtechs. All of these cases have proven their ability to generate business value in a broad scope of business applications. We aim to further thinking on how life insurers could leverage data analytics to support their business ambitions. We also present feedback from life insurance industry data…

A European insurance leader works with Milliman to process raw telematics data and detect driving behaviour
White Paper
The digital revolution has been disrupting industries for some years now. At a time when users increasingly expect trust, responsiveness and transparency, the real challenge is often to provide new services adapted to their emerging needs. The insurance world is not immune to this revolution and telematics is an excellent illustration of this change initiated by insurtech companies. This article focusses on the future of motor insurance and telematics, providing feedback on some of the projects…

Machine Learning : Méthodes d’apprentissage statistique en assurance
White Paper
Le marché de l’assurance a rarement été marqué par un environnement aussi difficile qu’au cours de ces dernières années. Cette situation met encore davantage en lumière la nécessité au sein des compagnies d’effectuer les diagnostics pouvant aider le management dans sa prise de décisions. L’utilisation de méthodes innovantes et rapides à mettre en oeuvre comme les méthodes d’apprentissage statistique (ou « machine learning ») peut être un avantage compétitif déterminant dans ce contexte.

Méthodes d’apprentissage appliquées à la tarification non-vie
Master's thesis
Insurance pricing is a core business for insurance companies. Our aim here is to tackle the main methods used in non-life pricing and in particular within automobile insurance. The issue at stake is to have a better understanding of the ins and outs of machine learning systems applied to pricing. We compare them to more classical methods, like the very widespread generalized linear model (GLM). To begin with, we highlight a general mathematical framework for estimators in statistics. This…
Insurance pricing is a core business for insurance companies. Our aim here is to tackle the main methods used in non-life pricing and in particular within automobile insurance. The issue at stake is to have a better understanding of the ins and outs of machine learning systems applied to pricing. We compare them to more classical methods, like the very widespread generalized linear model (GLM). To begin with, we highlight a general mathematical framework for estimators in statistics. This enables us to compare the different methods. In the first part we present the automobile database used, which gathers half a million of insured. We also underline how to deal with outliers in the data. The second part focuses on the GLM. The aim of the third and fourth parts is to lay down the principles and the full computation of machine learning methods. We specifically go on about the classification and regression trees (CART) and the ensemble methods like bagging, random forests, and boosting. In the last part we eventually draw an analysis between all the results. We conclude with the advantages of the new non-parametric approaches based on trees. They are indeed easy to implement and they offer a synthetic vision of the insurance portfolio. Yet one needs to be cautious with these results. The high performance of the machine learning methods is linked to the database. If the data are the exact realization of a given parametric distribution then a regression model will fit almost perfectly. However, machine learning procedures give an opportunity to better understand the underlying risks of the portfolio, offering a new framework.
