Activision is partnering with the California Institute of Technology, or Caltech, to use Call of Duty player data in order to train an AI that will help curb trolling behaviour in multiplayer games, as the latest CoD, Modern Warfare 2, receives a huge update alongside Warzone 2. As part of a two-year project, Activision is working alongside professors and researchers at Caltech in order to cultivate artificial intelligence tools that can detect and help moderate toxic behaviour in online games. The project will utilise Activision’s own data regarding how players interact in multiplayer games, with the developers and engineers behind Call of Duty working closely with the team at Caltech.
