Abstract: A method and apparatus for adjusting a boot option of a server, a non-volatile readable storage medium, and an electronic apparatus are provided. The method for adjusting a boot option of a server includes: invoking, in response to detecting failure of an adjustment operation executed for a boot option of a target server, a first detection parameter corresponding to the target server; detecting a connection state of a universal serial bus (USB) port of the target server according to the first detection parameter; and adjusting, in response to determining that the USB port connection state is used to indicate that a target USB port connected to a target USB device is provided on the target server, a boot option of a USB device to a target boot option of the target server.

Abstract: Disclosed are a training method, a method for using a model, a wireless communication method, and an apparatus. The training method includes: generating, by a first device, a second data set according to a first data set, where data in the second data set is low-dimensional representation data of data in the first data set; and training, by the first device according to the second data set, a first model used for wireless communication.

Abstract: The present application provides a model training method, a channel adjustment method, an electronic device, and a computer readable storage medium, the model training method includes: collecting historical samples, with the historical samples including first scheduling information and first information corresponding to a historical data transmission, the first information representing a result of cyclic redundancy check, and the first scheduling information including first intermediate variable information in an adaptive modulation and coding process; and performing model training according to the historical samples to obtain a first prediction model, and during the model training, the first scheduling information is used as an input of the first prediction model, the first information is converted into second information corresponding to the historical data transmission to be used as an output of the first prediction model, and the second information represents a probability value of the result of the cycli

Abstract: The present invention discloses fiducial marker systems or tag systems and methods to detect and decode a tag. In one aspect, a tag comprises four corners. Two upper corners are interconnected to form a detection area. Two lower corners are interconnected to form another detection area. The detection areas are interconnected by a path. The path divides the space between the detection areas into two coding areas. In another aspect, a tag comprises four corners. The four corners are interconnected by multiple paths. The multiple paths divide the space defined by the four corners into multiple coding areas.

Abstract: The present disclosure provides a method and device for forwarding a priority tag across network segments. The method includes the following steps: performing networking by using a Virtual Local Area Network (VLAN) interface to form a network; enabling a VLAN Class Of Service (COS) and differentiated service code point in a priority tag of a message transmitted in the network to correspond to each other; in response to layer-3 forwarding of the message, using the differentiated service code point priority tag for the message, and copying a VLAN COS value of the message at an entry of a switch to a VLAN COS value of the message at an exit; and in response to subsequent layer-2 forwarding of the message, using the VLAN COS priority tag for the message to distinguish a priority of the message.

Abstract: The present invention discloses fiducial marker systems or tag systems and methods to detect and decode a tag. The tag comprises a plurality of cells arranged in a grid pattern. The plurality of cells forms a square or rectangular shape. Each cell is in square or rectangular shape and has either black, white, or gray grayscale. Any two cells that share a common borderline should have different grayscales; and the four corner cells of the tag are all in black.

Abstract: A double-threshold mechanism is used for implementing the follow-me function of a mobile robot. Initially, a user comes to a mobile robot and turns on its follow-me function. Then, the mobile robot is in the follow-me mode or can simply be described as following the user. When the user moves away from the robot, the robot determines whether the distance between itself and the user exceeds a first distance threshold. If so, the robot starts moving to follow the user. Otherwise, the robot stays put. While following the user's movement, the robot continues to monitor the distance between itself and the user. When the robot determines that the distance between them is less than a second distance threshold—because the user has slowed down or stopped, for example—the robot stops moving. The second distance threshold is lower than the first distance threshold.

Abstract: A delayed direction change mechanism is used for implementing the follow-me function of a mobile robot. The mobile robot intentionally avoids following or reacting to a user's abrupt change of direction that exceeds a first threshold. Instead, the robot waits until the user's moving direction stabilizes and then determines its moving direction based on the user's then moving speed, direction, and/or position. A user's moving direction may be considered as stabilized if its change has always been less than or equal to a second threshold during a predetermined timeframe (e.g., 3 seconds).
