1. A method comprising:
causing a machine to perform one or more navigation operations based at least on a map, the one or more navigation operations including one or more of braking, steering, or accelerating and the map being updated, at least by:
obtaining, using a first learning model, a first object classification of an object corresponding to first sensor data of a first sensor modality;
obtaining, using a second learning model, a second object classification of the object corresponding to second sensor data of a second sensor modality, the second object classification being different than the first object classification;
determining an object class of the object based at least on:
the first object classification;
the second object classification;
a first degree of accuracy of the first learning model with respect to its ability to classify objects that are included in the first object classification; and
a second degree of accuracy of the second learning model with respect to its ability to classify objects that are included in the second object classification; and
updating the map based at least on the object class.
