1. A computer-implemented method of identifying an entity, the method comprising: identifying, by one or more computing devices, from a plurality of images, one or more images that depict an entity; determining, by the one or more computing devices, one or more candidate entity profiles from an entity directory based at least in part on the one or more images that depict the entity; providing, by the one or more computing devices, the one or more images that depict the entity and the one or more candidate entity profiles as input to a machine learning model; generating, by the one or more computing devices, one or more outputs of the machine learning model, each output comprising a match score associated with an image that depicts the entity and at least one candidate entity profile; and updating, by the one or more computing devices, the entity directory based at least in part on the one or more generated outputs of the machine learning model.
