In various examples, control policies for controlling agents may be learned from demonstrations capturing joint states of entities navigating through the environment. A control policy may be learned mapping joint states to control actions, where the joint states are between agents, and the control actions are of at least one of the agents. The control policy may be learned to define the mappings as control invariant sets of the joint sates and the control actions. The control policy may be used to determine one or more functions that compute, based at least on a joint state between entities, output indicating a likelihood of collision between the entities operating in accordance with the control policy. Using the output, current and/or potential states of the environment may be evaluated to determine control operations for a machine, such as a vehicle.

Learning autonomous vehicle safety concepts from demonstrations

In various examples, cost probability distributions corresponding to predicted locations of an object in an environment and potential locations for a machine in the environment and may be evaluated using corresponding observed costs corresponding to the machine and the object. The cost probability distributions may be evaluated based on comparing the observed costs to threshold values, which may be determined based on sampling a predicted cost function. A threshold value may be selected to provide false-positive rate and/or false-negative rate guarantees for anomaly detection. Control operations may be performed based on results of the evaluation of the cost probability distributions. For example, based on the results, a motion planner may reuse a planned trajectory for a future planning cycle (e.g., thereby avoiding re-planning computations) or generate and/or select a new planned trajectory (e.g., based at least on one or more anomalies being detected).
