  • Publication number: 20250164966
    Abstract: Systems and methods are disclosed for determining a policy to recommend transition in a position-representing space for a robotic device using a multi-critic architecture. To learn policy in a multi-critic architecture, a set of critics is defined pertaining to a position-representing space where each critic corresponds to a different objective function such as reach-reward, discovery-reward, and safety-reward. For each one of the critics of the set of critics, a learned value function in position-representing space is determined. The policy is learned based on the weighted feedback of the learned value functions to recommend transitions that are safe in the position-representing space. The multi-critic architecture minimizes interference between multiple reward functions and learns a safe and stable policy for the robotic device.

  • Patent number: 10663829
    Abstract: A blue light-blocking structure and manufacturing method thereof, a display device and an operation method thereof are provided. The blue light-blocking structure includes a first transparent dielectric layer, a second transparent dielectric layer and an electro-refractive index adjusting layer. The second transparent dielectric layer is provided on a side of the first transparent dielectric layer. The electro-refractive index adjusting layer is provided between the first transparent dielectric layer and the second transparent dielectric layer. The electro-refractive index adjusting layer is configured to change the refractive index to the blue light transmitted through the electro-refractive index adjusting layer under the action of an electrical field applied between a first side of the electro-refractive index adjusting layer near the first transparent dielectric layer and a second side near the second transparent dielectric layer.
