  • Deep Learning Indaba 2018: AI Ethics and Policy [Facilitator and Organiser with Muthoni Wanyoike] - This session will tackled the intersections of AI/ML, Ethics and Policy on the continent. Session will be a blend of a practical interactive Ethics session, a talk on fairness and robust discussion via an expert panel made up of researchers, practitioners, policy makers. At the end of the day, we would like to answer: How do we work to inject our own values into AI/ML development in Africa, allow a progressive environment for development and protect our communities? [Link]
