19. A processor comprising:
one or more processors to:
compute, using one or more neural networks:
first data associated with a first map representing at least a first portion of an environment, the first map including one or more first pixels indicating a first future location, the first map being associated with a first future time;
second data associated with a second map representing at least a second portion of the environment, the second map including one or more second pixels indicating a second future location, the second map being associated with a second future time that is after the first future time; and
third data representative of a vector field associated with the second map;
determine the second future location indicated by the second map is associated with an actor;
determine one or more vectors from the vector field corresponding to the second future location, the one or more vectors indicating a pixel distance between the second map and the first map;
determine based at least on the one or more first pixels from the first map being associated with the pixel distance from the one or more second pixels from the second map, that the second future location associated with the second future time is related to the first future location associated with the first future time that precedes the second future time; and
determine based at least on the second future location being related to the first future location, that the first future location indicated by the first map is also associated with the actor.
