Conditional expectation network for SHAP

no code implementations20 Jul 2023 Ronald Richman, Mario V. Wüthrich

A very popular model-agnostic technique for explaining predictive models is the SHapley Additive exPlanation (SHAP).

Isotonic Recalibration under a Low Signal-to-Noise Ratio

no code implementations6 Jan 2023 Mario V. Wüthrich, Johanna Ziegel

Insurance pricing systems should fulfill the auto-calibration property to ensure that there is no systematic cross-financing between different price cohorts.

A Discussion of Discrimination and Fairness in Insurance Pricing

no code implementations2 Sep 2022 Mathias Lindholm, Ronald Richman, Andreas Tsanakas, Mario V. Wüthrich

This is particularly the case in insurance pricing where protected policyholder characteristics are not allowed to be used for insurance pricing.

Model selection with Gini indices under auto-calibration

no code implementations28 Jul 2022 Mario V. Wüthrich

The Gini index does not give a strictly consistent scoring rule in general.

A multi-task network approach for calculating discrimination-free insurance prices

no code implementations6 Jul 2022 Mathias Lindholm, Ronald Richman, Andreas Tsanakas, Mario V. Wüthrich

Here, we address this issue by using a multi-task neural network architecture for claim predictions, which can be trained using only partial information on protected characteristics, and it produces prices that are free from proxy discrimination.

LocalGLMnet: interpretable deep learning for tabular data

no code implementations23 Jul 2021 Ronald Richman, Mario V. Wüthrich

Deep learning models have gained great popularity in statistical modeling because they lead to very competitive regression models, often outperforming classical statistical models such as generalized linear models.

Assessing asset-liability risk with neural networks

no code implementations26 May 2021 Patrick Cheridito, John Ery, Mario V. Wüthrich

We introduce a neural network approach for assessing the risk of a portfolio of assets and liabilities over a given time period.
