Sony’s new AI agent achieves superhuman Gran Turismo Sport scores

One of the best things about computers is that they can learn just as much from a simulation as they can from so-called ‘real world’ experiences. That means, given the proper simulator, we can teach AI to drive cars without ever putting a single human in danger. Just about every AI company trains their driverless vehicle algorithms using simulations. Until now, the simulators themselves weren’t all that interesting. They’re mostly just physics engines designed to be interpreted by a neural network. But Sony just unveiled the most popular autonomous driving simulator ever: Gran Turismo Sport. In case you’re not a gamer: this isn’t advanced software designed to train AIs, it’s a game. And not just any game but the latest in one of the most beloved racing simulation series in history Researchers from the University of Zurich and Sony AI Zurich recently published a pre-print paper showcasing the development of an autonomous agent designed to beat the best human players at the game. Per the team: Among racing games, Gran Turismo Sport (GTS) is known as a highly realistic driving simulation, modelling phenomena, such as the influence of tires’ temperature and a car’s current fuel level on traction. Therefore, similarly to real-world racing, the optimal trajectory (i.e., the trajectory leading to the fastest lap time) for a car in GTS depends not only on the geometry and properties of the track, but also on various (a priori unknown) physical characteristics and states of the car. Due to its similarity to real…Continue readingSony’s new AI agent achieves superhuman Gran Turismo Sport scores
