How do we know how well the gnn reconstructs the target state vector from the truth vector captured by the sensors?

Answer 1

1. There is a metrics object to calculate the tracking accuracy, which is a counterpart of the track assignment metrics object. The name of that object is: trackErrorMetrics.
2. You can see an example of the outcome of the track error metrices in this example. If you open the example, you can click on the helperRunTracker function to see it in use.
3. You can see another example of it being used in this example. Look for the lines of code in the section Track Using an EKF in Cartesian Coordinates
