Abstract: An autonomous vehicle, cognitive system for operating an autonomous vehicle and method of operating an autonomous vehicle. The cognitive system includes one or more hypothesizer modules, a hypothesis resolver, one or more decider modules, and a decision resolver. Data related to an agent is received at the cognitive system. The one or more hypothesizer modules create a plurality of hypotheses for a trajectory of the agent based on the received data. The hypothesis resolver selects a single hypothesis for the trajectory of the agent from the plurality of hypotheses based on a selection criteria. The one or more decider modules create a plurality of decisions for a trajectory of the autonomous vehicle based on the selected hypothesis for the agent. The decision resolver selects a trajectory for the autonomous vehicle from the plurality of decisions. The autonomous vehicle is operated based on the selected trajectory.

Abstract: A method using unsupervised velocity prediction and correction for urban driving from sequences of noisy position estimates includes: performing a vehicle velocity prediction for one or more other vehicles in a vicinity of a host automobile vehicle; calculating a first heuristic based on a uniformity test; calculating a second heuristic based on a vehicle speed of the one or more other vehicles; combining the first heuristic and the second heuristic using a weighted sum; determining an uncertainty mask applying the combined first heuristic and the second heuristic and a heuristic threshold; and applying the uncertainty mask to identify a velocity correction for use by the host automobile vehicle.

Abstract: A method for performing object detection during autonomous driving includes: performing 3D object detection in a 3D object detection segment; uploading an output of multiple sensors in communication with the 3D object detection segment to multiple point clouds; transferring point cloud data from the multiple point clouds to a Region Proposal Network (RPN); independently performing 2D object detection in a 2D object detector in parallel with the 3D object detection in the 3D object detection segment; and taking a given input image and simultaneously learning box coordinates and class label probabilities in a 2D object detection network operating to treat object detection as a regression problem.
