Classification: CPC B  G | IPC B  G

Claim 17:
18. A system, comprising:

at least one processor; and

a memory storing instructions thereon that, when executed by the at least one processor, cause the at least one processor to:
assign a set of initial physical states to a set of objects for a set of simulated driving scenarios;
generate the set of simulated driving scenarios using the initial physical states of the objects in the set of objects;
determine one or more failed driving scenarios in the set of simulated driving scenarios;
exclude the one or more failed driving scenarios from the set of simulated driving scenarios, wherein the one or more failed driving scenarios comprise a driving scenario where acceleration or deceleration values of one or more objects in the set of objects are higher or lower than one or more specified threshold values;

train a machine learning model using first samples of the set of simulated driving scenarios;
obtain tuning data comprising second samples of the set of simulated driving scenarios;
tune the trained machine learning model with the tuning data;
optimize a loss function of predictions output by the tuned machine learning model; and
cause a vehicle to operate in an environment using the tuned machine learning model.
