Artificial intelligence (AI) offers great promise for solving business and social problems, but it also risks inadvertently discriminating against minority and marginalised groups. The EU-funded MAMMOth project tackles this bias by focusing on multi-discrimination mitigation for tabular, network and multimodal data. Working with computer science and AI experts, the project will create tools for fairness-aware AI which ensure accountability with respect to protected attributes like gender, race and age. The project will also engage with communities of vulnerable and/or underrepresented groups in AI research to ensure that user needs and pains are truly at the centre of the agenda. The end goal is to develop pilot projects for finance/loan applications, identity verification and academic evaluation.
