Team sports tactics analysis systems often focus on game event detection, which are unable to analyze the tactics in detail and suggest better tactics for training. We introduce a novel tactics training system that is able to assess the state of the basketball game in detail, and find better defense tactics. Instead of tracking only player/ball positions, our system studies players’ attributes together with their court positions to accurately estimate each player’s offense threat or defense ability. We then formulate an optimization problem to find the defense tactics that could minimize the offense team’s threat. The optimal defense tactics found by our system have received favorable evaluations by three professional basketball coaches in Beijing Sports University from a professional point of view, and as opposed to some well known defense conventions, our system opens up new promising defense tactics and possibilities.
