Abstract: The present disclosure discloses a method for adding group members. When the first user needs to add a new member to the target group in the instant messaging system, in response to triggering of a first user, an imported target document is obtained, and the target document includes user information of one or more second users in an instant messaging system. After obtaining the target document, the target document is parsed to obtain user information of one or more second users included in the target document in the instant messaging system. After obtaining the user information through parsing, the one or more second users will be added to the target group in the instant messaging system based on the user information.

Abstract: The present disclosure relates to the technical field of plasma cleaning, and provides a plasma cleaning head for an optical member and a plasma cleaning device, including a plasma circulation assembly having a hollow shape and a lens frame mounted on the plasma circulation assembly, wherein the plasma circulation assembly is provided with an outlet port which is larger than an ejection port adapted to eject a plasma and is adapted to diffuse the plasma, and the lens frame is in communication with and surrounds the outlet port, and the lens frame is adapted to embed an optical lens body so that the optical lens body is arranged opposite to the outlet port to help improve dispersion and stability of the plasma flowing from the outlet port to the optical lens body, and helps to promote the energy absorption of the plasma by the optical lens body.

Abstract: Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for receiving first and second data sets, both the first and second data sets including structured data in a plurality of columns, for each of the first data set and the second data set, inputting each column into an encoder specific to a column type of a respective column, the encoder providing encoded data for the first data set, and the second data set, respectively, providing a first multi-dimensional vector based on encoded data of the first data set, providing a second multi-dimensional vector based on encoded data of the second data set, and outputting the first multi-dimensional vector and the second multi-dimensional vector to a loss-function, the loss-function processing the first multi-dimensional vector and the second multi-dimensional vector to provide an output, the output representing matched data points between the first and second data sets.

Abstract: Embodiments of the application disclose a road marking recognition method, a map generation method, and related products. The road marking recognition method includes that: a base map of a road is determined according to acquired point cloud data of the road, pixels in the base map being determined according to reflectivity information of an acquired point cloud and position information of the point cloud; a pixel set composed of the pixels in the base map that road markings include is determined according to the base map; and at least one road marking is determined according to the determined pixel.
