Abstract
Techniques for determining whether a machine-learned model has improved or regressed in response to an update, as well as verifying whether those improvements or regressions impact overall vehicle safety, are described herein. The techniques may include running a simulation in which a simulated vehicle traverses a simulated environment. During the simulation, sensor data associated with the simulated environment may be input to the machine-learned model, which is configured for use in the real vehicle. As such, perception data outputs associated with objects detected in the simulated environment may be received from the machine-learned model during the simulation, and one or more error models may be generated based on the outputs and a ground truth. If the error model indicates that an error meets or exceeds a threshold error, the machine-learned model may be updated to reduce the error below the threshold.
