A Practical Guide on Graphical Model Validation
Mario V. Wüthrich
This manuscript formalizes the most popular model validation tools used in general insurance actuarial modeling. These include graphical tools like calibration plots, actual-vs-exp…
Many Optimizers But Only One Training Path: Repeated Resampling for Adaptive Optimizer Selection
Ronald Richman, Mario V. Wüthrich
An optimizer is usually chosen before training a deep neural network and then kept fixed. Treating optimizer choice as a hyperparameter could boost performance, but it requires sev…
The Balance Property: The Constrained Case, with a View on Risk Sharing
Mario V. Wüthrich
The balance property is an important property of fitted statistical models deployed for insurance pricing. It guarantees that the total actuarial price in the fitted model is equal…
Insurance Pricing Optimization via Off-Policy Evaluation
Sascha Günther, Dimitri Semenovich, Mario V. Wüthrich
Traditional insurance pricing relies on risk-based principles that ensure actuarial fairness and solvency but do not explicitly account for policyholders' price sensitivity. We for…
Measures of predictive accuracy, miscalibration and discrimination
Łukasz Delong, Mario Wüthrich
We study the evaluation of real-valued point predictors under the decision-theoretic framework of mean-consistent loss functions given by the Bregman divergences. We first derive a…
A Note on the Generalized Cape Cod Reserving Method
Ronald Richman, Mario V. Wüthrich
Claims reserving is one of the most important actuarial tasks in non-life insurance modeling. There are several popular methods to perform claims reserving such as the chain-ladder…
