Today on War Stories, Ars Technica is joined by Dan Greenawalt, Creative Director of the Forza franchise, who takes us through the colossal potential (and many challenges) of utilizing deep neural networks to build sophisticated racing AI. Beginning with the original Drivatar AI in Forza Motorsport for XBOX in 2005, Greenawalt and his colleagues experimented with computer learning, refining their methods from iteration to iteration. It was once the AI system was unshackled from local hard drives and placed online in Forza Motorsport 5, however, that the floodgates truly opened. As the AI rapidly evolved, producing unexpected new behaviors, the Forza team quickly learned how challenging it would be to wield this two-edged sword in creating realistic opponents.
