This research objective focuses on data mining, which is quickly becoming a popular artificial intelligence technique used by tax administrations for better fraud detection. However, many challenges still exist. One of the main challenges is explaining the predicition made by complex algorithms. Within this research objective, we explore the opportunities of tackling this challenge of explainable AI by making use of counterfactual explanations.
