Abstract: Sports monitoring knowledge are the high-resolution spatiotemporal observations of a aggressive occasion. The growing collection of these knowledge in professional sport permits us to deal with a fundamental drawback of fashionable sport: find out how to attribute worth to particular person actions? Taking advantage of the smoothness of ball and player motion in tennis, we present a useful data framework for estimating anticipated shot value (ESV) in continuous time. Our method is a three-step recipe: 1) a generative mannequin for a full-resolution purposeful representation of ball and player trajectories using an infinite Bayesian Gaussian mixture model (GMM), 2) conditioning of the GMM on observed positional information, and 3) the prediction of shot outcomes given the functional encoding of a shot event. From the ESV we derive three metrics of central interest: value added with shot taking (Vast), Shot IQ, and value added with court coverage (VACC), which respectively attribute value to shot execution, shot selection and movement around the court docket.
