Abstract: Technologies and techniques for vehicle perception. Contours are extracted from image data, and a first and second contour of a current image and next image are determined along a plurality of image row boundaries, wherein the contours includes a plurality of contour points linked to each other via respective edges. An image velocity vector is applied to project each of the plurality of first contour points to the next image, wherein at least some of the projected first contour points are not located on an image row boundary. The projected contour points are processed to determine projected edges forming a projected link between each projected contour point. The projected contour points are moved along the projected link to align each of the moved projected contour points to a respective image boundary. Each of the moved projected contour points are then linked to each of the second contour points.

The simulator may carry out experiments in open natural water bodies by use of its own autonomous sailing capability under remote wireless control and may acquire parameters such as dynamic characteristics and spatial configuration and the like of a deep-sea mining hydraulic lift subsystem in real time.

Abstract: According to an example embodiment, a device is configured to a deep reinforcement learning, DRL, agent to simulate the behaviour of a network component. The DRL agent takes the network state and user traffic as inputs. It generates the next network state and user performances. A training algorithm of the simulator is configured for the DRL agents and it is derived to deal with the property of time-correlation in network components. The simulator uses a training algorithm so that it enables robust inference under a limited number of transitions collected with the real network components and users. It is derived with state augmentation by using an autoencoder architecture. It is also configured by a reward estimation algorithm by using local regression, for example with a Gaussian Process.
