1. A system comprising:
a sensor within an autonomous or a semi-autonomous vehicle, the sensor comprising a Lidar, a radar, or a camera;
and one or more processors configured to:
perform a validation of the sensor to determine whether the sensor is calibrated;
in response to performing the validation, and determining that the sensor is uncalibrated, determining a type or a mode of an error handling procedure, selected from error handling procedures based on a historical rate of success associated with the type or the mode of the error handling procedure, wherein the error handling procedures comprise initiating a backup sensor, recalibrating the sensor, eliminating erroneous data from the sensor, and issuing an alert; and
perform the type or the mode of the error handling procedure.
