Artificial intelligence (AI) is widely used in a large number of sectors due to the benefits of automation and optimisation. However, AI can be also a source of bias and discrimination that needs to be controlled, measured and avoided. In addition, there is a lack of knowledge on repairing and assessing bias in existing AI systems and on designing new bias-free AI tools. The EU-funded AEQUITAS project will change this by developing a controlled experimentation environment to help AI producers to increase awareness of bias produced by AI systems and evaluate and (possibly) repair existing AI systems. It will also provide guidelines for fair-by-design AI systems and raise awareness about risks from AI if not adequately handled and managed.
