“Treat Everyone Fairly: Enabling an Unbiased and Explainable Algorithmic Decision Making” by Prof. Amy Wenxuan Ding – emlyon business school
Driven by big data and rapid improvements in computing power, many firms and organizations are interested in deploying various AI and machine learning methods to create values and improve their decision-making. Although conventional machine learning methods have shown a great social impact and a good performance in many application areas, the European Union’s new General Data Protection Regulation raises emerging concerns on the potential discriminatory and unexplainable decisions generated by conventional machine leaning models. Thus, how to eliminate discrimination and produce trans-parent and explainable decision-making becomes an urgent and important challenge in AI and machine learning communities.
There are two fundamental issues in current machine learning methods: First, they rely on aggregate-level learning using a data sample consisting of different sub-jects. Thus, sample selection bias may occur, resulting in biased decisions when a subject is not in the same population as those in the training sample. Second, the learning processes are not theory-driven and focus on correlations among feature variables in data samples rather than their causal effects. Therefore, the produced outcomes are un-interpretable.
This paper presents a novel theory-based individual dynamic learning model to overcome discrimination and emphasize on a causal inference to enable explanation. The model (1) uses limited data from each individual subject without employing other subjects’ data to overcome the discrimination issue; and (2) learns the underlying data generating process from individual subject to identify the corresponding causality mechanism to achieve a fair and interpretable decision. Using a real-world credit and risk assessment as the context, we empirically test our model and demonstrate a greater performance comparing to conventional supervised learning models and decision tree models in terms of fairness, transparency, and accuracy.
