OptiGrad: A Fair and more Efficient Price Elasticity Optimization via a Gradient Based Learning

no code implementations16 Apr 2024 Vincent Grari, Marcin Detyniecki

The reverse-engineered nature of traditional models complicates the enforcement of fairness and can lead to biased outcomes.

On the Fairness ROAD: Robust Optimization for Adversarial Debiasing

1 code implementation27 Oct 2023 Vincent Grari, Thibault Laugel, Tatsunori Hashimoto, Sylvain Lamprier, Marcin Detyniecki

In the field of algorithmic fairness, significant attention has been put on group fairness criteria, such as Demographic Parity and Equalized Odds.

A Fair Pricing Model via Adversarial Learning

no code implementations24 Feb 2022 Vincent Grari, Arthur Charpentier, Marcin Detyniecki

In this paper, we will show that (2) this can be generalized to multiple pricing factors (geographic, car type), (3) it perfectly adapted for a fairness context (since it allows to debias the set of pricing components): We extend this main idea to a general framework in which a single whole pricing model is trained by generating the geographic and car pricing components needed to predict the pure premium while mitigating the unwanted bias according to the desired metric.

Fairness without the sensitive attribute via Causal Variational Autoencoder

1 code implementation10 Sep 2021 Vincent Grari, Sylvain Lamprier, Marcin Detyniecki

In recent years, most fairness strategies in machine learning models focus on mitigating unwanted biases by assuming that the sensitive information is observed.

Learning Unbiased Representations via Rényi Minimization

1 code implementation7 Sep 2020 Vincent Grari, Oualid El Hajouji, Sylvain Lamprier, Marcin Detyniecki

We leverage recent work which has been done to estimate this coefficient by learning deep neural network transformations and use it as a minmax game to penalize the intrinsic bias in a multi dimensional latent representation.
