Gravity Example: 0.04s of Computation

Recently, we posted about a way to redefine gravity in terms of a joint model that can be used to quantify defensive interaction, offensive spacing, and spatio-temporal motion of a possession. The result yields a sparse N x 2P x Q x R x S x Z tensor that characterizes the interactions of players, locations on the court,…
