Abstract: A method of providing tactical information for team sports is disclosed. The method includes acquiring a plurality of player tracking data sets for a plurality of players, acquiring role assignment information using the plurality of player tracking data sets, determining a dominant role assignment based on the plurality of role assignments, determining at least one irregular role assignment from the plurality of role assignments in consideration of the dominant role assignment, acquiring a plurality of space information sets associated with the target period for each of the plurality of role indices based on the remaining role assignment information other than the at least one irregular role assignment and some of the player tracking data sets corresponding to the remaining role assignment information and updating the role assignment information using the plurality of space information sets.

Abstract: A method for providing exercise load information of a target entity is provided. The method includes obtaining a target data set of the target entity for a target exercise session including a plurality of time units, wherein the target data set includes a sequence of kinematic information of the target entity for each of the plurality of time units; and determining, based on the target data set, an estimated load index reflecting a level of exercise load of the target entity for the target exercise session using an artificial neural network (ANN).
