Elon Musk's startup OpenAI develops technique to train AI 
Artificial intelligence (AI) focused startup OpenAI, co-founded by Elon Musk, has developed a technique to train AI systems by debating with each other. The 'Debate Game' includes two debaters who describe an image and the judge who determines which debater is telling the truth. However, the game currently does not involve machine learning and can be played at a human-level.
