Google's DeepMind AI has been trained to play table tennis, and it can beat human players - but only at a moderate level. According to a recent study, the AI-controlled robot arm defeated beginners and intermediate players, but was outplayed by advanced players. The researchers used a customized version of DeepMind's learning algorithm to train the robot, which learned specific skills like creating top spin and using backhand targeting. While the AI showed promise in some areas, it struggled with high balls and found backhand shots more challenging than forehand ones.
