In my talk, I will first briefly present ELLIS Alicante, the only ELLIS unit that has been created from scratch as a non-profit research foundation devoted to responsible AI for Social Good. Next, I will provide an overview of AI with a focus on the ethical implications and limitations of today’s AI systems, including algorithmic discrimination and bias. On this topic, I will present a few examples of our work on uncovering and mitigating both human and algorithmic biases with AI. On the human front, I will present the body of work that we have carried out in the context of AI-based beauty filters that are so popular on social media. On the algorithmic front, I will explain the main approaches to address algorithmic discrimination and I will present three novel methods to achieve fairer decisions
