These AI-generated tennis matches are both eerie and impressive

Thanks to the coronavirus pandemic, there was no Wimbledon Championship this year. But that didn’t stop a team of researchers from Stanford University simulating the annual tournament with the help of artificial intelligence.

The team trained their AI using a database of annotated footage. The cyclical nature of tennis helped them create a statistical model that predicts how stars like Novak Djokovic and Roger Federer will play in certain situations.

The model does this by taking into account common tennis strategies and the tendencies of each player. Through its training, it knows, for instance, that Djokovic likes to hit the ball toward his opponent&aposs weak side. Similarly, the model also considers how players tend to position themselves while waiting for their opponent to return the ball. It will consistently place Federer closer to the baseline than Rafael Nadal, reflecting how those two play the game in real life. According to the team that created the AI, it&aposs this behavioral aspect that separates their project from past attempts to create a system that can simulate tennis play.

Those capabilities allow the system to create potentially endless what-if scenarios. It can generate footage of Federer playing against himself or Serena Williams. It can even extrapolate how a match may have played out differently had a single shot landed in a different location. What&aposs more, the system allows you to control a player&aposs shot placement and recovery position, so there&aposs the potential a studio could adapt it for gaming.

Of course, it’s not perfect. While the researchers did their best to hide potentially distracting visual artifacts like changing lighting and player clothing, there are moments where the clips look more like they’re ripped straight from a 90s FMV game. As you can see from the clip above, fans and officials don&apost move at all. Another factor that breaks the illusion is that the ball and players don&apost cast shadows. It also looks like they&aposre skating across the surface of the court. Still, it&aposs an impressive system that could have a lot of fun applications.
