Debate Game
In 2018, OpenAI launched the Debate Game, which teaches machines to debate toy problems in front of a human judge. The purpose is to research whether such an approach may assist in auditing AI decisions and in developing explainable AI.
The single pixel debate game is played between two debaters and a judge. One debater tells the truth, the other lies. An image is visible to the two debaters, and they can draw rectangles on the image and talk to the judge. The judge sees only the rectangles: the image is hidden. Each debater is also allowed to reveal a single pixel to the judge. The pixel must be chosen carefully, since they can only reveal one pixel total over the whole debate.
