This event will gather up to 12 teams from around the world to engage in a challenge using open spending data, development indicators, and the recently released web-based modelling app from the Policy Priority Inference research programme. The organisers would like to invite anyone interested in the intersection of sustainable development, artificial intelligence, open government, and computational social science to attend this one-of-a-kind event. The opening and closing sessions will be open to the public (no need to have team), while the challenger teams will work on a case study for a week with mentorship facilitated by the organisers.
