  • Publication number: 20250115278
    Abstract: Systems and methods for generating adversarial driving scenarios for autonomous vehicles. An artificial intelligence model can compute an adversarial loss function by minimizing the distance between predicted adversarial perturbed trajectories and corresponding generated neighbor future trajectories from input data. A traffic violation loss function can be computed based on observed adversarial agents adhering to driving rules from the input data. A comfort loss function can be computed based on the predicted driving characteristics of adversarial vehicles relevant to comfort of hypothetical passengers from the input data. A planner module can be trained for autonomous vehicles based on a combined loss function of the adversarial loss function, the traffic violation loss function and the comfort loss function to generate adversarial driving scenarios. An autonomous vehicle can be controlled based on trajectories generated in the adversarial driving scenarios.

  • Publication number: 20240210664
    Abstract: This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first lens element group and a second lens element group. The first lens element group and the second lens element group each include a plurality of lens elements. In different use scenarios, the second lens element group can be moved to change a distance between the first lens element group and the second lens element group, to change a focal length of the optical lens. This ensures that the optical lens in this application can achieve a good shooting effect in different use scenarios. In this application, the second lens element group is disposed within a back focal length range of the first lens element group. In this way, a total track length of the optical lens in this application can be small, so that the optical lens can be used within a thin electronic device.
