Abstract: A method and system for traversing a bounding volume hierarchy (BVH) structure associated with a given 3D scene using a ray tracing algorithm are provided. The method comprises: determining an escape probability value for a given node of the BVH structure of a given ray traversing the given node without reflecting off any mesh element contained therein; propagating a ray in the given 3D scene that intersects the respective bounding volume of the given node; in response to determining that the ray is to traverse the respective bounding volume, determining whether the ray is to traverse or to reflect off an other respective bounding volume; and in response to determining that the ray is to reflect off the respective bounding volume: rendering a mesh element contained in the respective bounding volume of the given BVH node.

Abstract: There is described a method for decomposing a layer in an artificial intelligence (AI) model. A rank of decomposition is calculated based on a performance function of a processor. The layer is decomposed into a plurality of matrices based on the rank of decomposition. The layer is replaced in the AI model with the plurality of matrices to produce a compressed AI model.

Abstract: A tracking reference signal (TRS) burst transmission method and apparatus wherein a transmit end determines to send a first TRS burst in the first slot in a maximum channel occupancy time (MCOT), that is, the TRS burst is sent at a start moment of the MCOT, so that a receive end can obtain precise time-frequency synchronization as soon as possible. In addition, when a length of a first MCOT is greater than Y slots, in addition to sending the first TRS burst in the first slot in the MCOT, it is further determined to send a second TRS burst in a slot that is in the first MCOT and whose distance to a start slot of a previous TRS burst is Y slots, to improve effectiveness of the time-frequency synchronization and further improve the reliability of receiving the data at the receive end.

Abstract: This application discloses an information processing method, and the method may be applied to a computer like a vehicle or a handheld terminal. The vehicle is, for example, an intelligent vehicle or an intelligent connected vehicle. The method is used to implement a visual cognition process. The method includes: obtaining an image; inputting the image into a feature extraction model; obtaining, from the feature extraction model, a first feature map; inputting the first feature map into a first semantic recognition model; and obtaining, from the first semantic recognition model, first target semantic information. The visual cognition process is split and implemented by using two machine learning models, to facilitate optimization of the visual cognition process, improve accuracy of visual cognition, and further improve accuracy of a visual task.

Abstract: This application provides a resource reservation method and an apparatus. The method includes: receiving, by a node, a first message, where the first message carries a bandwidth value r1 of a resource requested to be reserved and a quantity Q1 of cycles occupied by the resource, the node maintains resource reservation states in K cycles, K is a positive integer, and Q1 is less than or equal to K; and updating, by the node, resource reservation states in Q1 of the K cycles based on the bandwidth value r1 and the quantity Q1. The node maintains the resource reservation states at a granularity of cycles. Therefore, the resource reservation states that need to be maintained by the node do not depend on a quantity of data flows processed by the node, and a performance requirement of a resource reservation for the node can be lowered.
