Assignee: MOTIONAL AD LLC
Field: Computer technology (Electrical engineering)
Classification: CPC B  G | IPC B  G

Claim 10:
11. A system comprising:
at least one processor; and
at least one non-transitory computer readable medium storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
receiving first data representing a plurality of scenarios for estimating a performance of a vehicle in conducting autonomous operations;
determining, for each of the scenarios:
a first metric indicating an observed performance of the vehicle in that scenario, wherein the first metric is determined based on at least one rule, and
a second metric indicating a degree of information gain associated with that scenario;

determining a Bayesian hierarchical model representing (i) one or more conditional independent properties of the performance of the vehicle according the plurality of scenarios and (ii) a submodularity of the degree of information gain associated with each of the scenarios;
selecting a subset of the scenarios based on the first metrics, the second metrics, and the Bayesian hierarchical model, wherein selecting the subset of the scenarios comprises determining that the subset of the scenarios is associated with a maximum degree of information gain from among the plurality of scenarios;
outputting second data indicative of the subset of the scenarios; and
estimating the performance of the vehicle based on the second data, wherein estimating the performance of the vehicle comprises at least one of:
performing a computerized simulation of the performance of the vehicle according to at least some of the subset of the scenarios, or
causing the vehicle to operate according to at least some of the subset of the scenarios.
