Claim 7:
8. A method performed by a controller comprising:
obtaining information about a first perception model installed in a vehicle moving from a first region to a second region;
determining a value of updating the first perception model;
determining whether the first perception model needs to be updated to a second perception model based on the value of updating the first perception model; and
transmitting the second perception model to the vehicle in response to determining that the first perception model needs to be updated to the second perception model,
wherein the first perception model is pre-trained with geolocation-based features related to the first region,
wherein the second perception model is pre-trained with geolocation-based features related to the second region, and
wherein the value of updating the first perception model is determined based on difference between accuracy of identifying objects in the second region using the second perception model and accuracy of identifying the objects in the second region using the first perception model.
