AI techniques for Simulating Behaviour using Facebook’s WW Social Media Simulation System

This talk describes Facebook's development of WW, its cyber-cyber digital twin, and, in particular, the way it uses artificial intelligence techniques for training bot behaviours. WW is a simulation of Facebook user behaviour on the real Facebook platform, which Facebook uses to test and optimise its products. There are inherently many foundational scientific challenges that come to the fore when attempting to safely, reliably and effectively simulate user behaviours at scale. The keynote talk will cover some existing practical and scientific work at Facebook, as well as outlining open problems and challenges for the research community for this research agenda at the intersection of AI and SE.
