This document describes change detection criteria for updating a sensor-based map. Based on detecting an indication of a registered object in the vicinity of a vehicle, a processor determines a difference between a characteristic of the registered object and a characteristic of a sensor-based reference map. A machine learning model is trained using self-supervised learning to identify change detection from inputs. The model is executed to determine whether the difference satisfies change detection criteria for updating the sensor-based reference map. If the change detection criteria are satisfied, the processor causes the sensor-based reference map to be updated to reduce the difference, which enables the vehicle to safely operate in an autonomous mode using the updated reference map for navigating the vehicle in a vicinity of a coordinate location of the registered object. The map can be updated concurrently as changes occur in the environment and without impacting performance, enabling real-time perception to support control and improve driving safety.
