Abstract: An electronic assembly includes a first electronic component, a second electronic component, and an electrical connector connecting the first electronic component and the second electronic component. The electrical connector includes a first multilayer circuit board and a terminal that includes a plurality of signal terminals and a plurality of ground terminals. Each signal terminal is electrically connected to a signal interface of the first electronic component and a signal interface of the second electronic component. Signal terminals configured to transmit a same signal form one group of signal terminals, and at least one ground terminal is disposed between two adjacent groups of signal terminals. The first multilayer circuit board includes at least one layer of first ground copper sheet. The first electronic component includes a second multilayer circuit board, and the second multilayer circuit board includes at least one layer of second ground copper sheet.

Abstract: The present disclosure relates to a category labelling method and apparatus, an electronic device, a storage medium, and a computer program. The method includes: detecting a video stream acquired by an image acquisition device to determine a detection result of a target video frame in the video stream, wherein the detection result includes a detected category, and the detected category includes at least one of: an object category of an object in the target video frame, and a scene category corresponding to the target video frame; and determining a category labelling result corresponding to the image acquisition device according to detection results of a plurality of target video frames.
