  • Publication number: 20240061435
    Abstract: Systems and methods for path planning with latent state inference and spatial-temporal relationships are provided. A system includes an inference module, a policy module, a graphical representation module, and a planning module. The inference module receives sensor data associated with a plurality of agents. The inference module also maps the sensor data to a latent state distribution to identify latent states of the plurality of agents. The latent states identify agents of the plurality of agents as cooperative or aggressive. The policy module predicts future trajectories of the plurality of agents at a given time based on sensor data and the latent states of the plurality of agents. The graphical representation module generates a graphical representation based on the sensor data and a graphical representation neural network. The planning module generates a motion plan for the ego agent based on the predicted future trajectories and the graphical representation.

  • Publication number: 20220230080
    Abstract: A system and method for utilizing a recursive reasoning graph in multi-agent reinforcement learning that includes receiving data associated with an ego agent and a target agent that are traveling within a multi-agent environment and utilizing a multi-agent central actor-critic framework to analyze the data associated with the ego agent and the target agent. The system and method also include performing level-k recursive reasoning based on the multi-agent actor-critic framework to calculate higher level recursion actions of the ego agent and the target agent. The system and method further include controlling at least one of: the ego agent and the target agent to operate within the multi-agent environment based on at least one of: an agent action policy that is associated with the ego agent and an agent action policy that is associated with the target agent.
