Abstract: A target sample including a sample feature, a first label, and a second label is obtained, where a user corresponds to the target sample, the first label indicates whether a target object is clicked on by the user, and the second label indicates whether the user implements a target behavior related to the target object. Model processing is performed on the sample feature using a prediction model with a first branch and first probability and a second branch and second probability. A first loss is determined based on a first label value and the first probability. When a predetermined condition is satisfied, the second loss is determined based on a second label value of the second label and the second probability, and a predicted loss of the target sample is determined based on the first loss and the second loss. Training the prediction model based on the predicted loss.

Abstract: The present disclosure discloses a method, a device, and a system for updating authenticating information in the field of Internet technologies. The method comprises: receiving a service processing request containing user information and service object information; extracting according to the user information, first authentication information associated with the service object information from prestored authentication information; authenticating the first authentication information; displaying an information update interface when the first authentication information fails to be authenticated; obtaining second authentication information from the information update interface; replacing the first authentication information with the second authentication information; authenticating the second authentication information; and processing the service processing request if the second authentication information is authenticated.

Abstract: Method, server, and storage medium for processing an order are provided.

Abstract: A manufacturing method of an alignment layer and a manufacturing method of a display substrate are provided. The manufacturing method of the alignment layer includes: providing a display substrate on which a patterned structure is formed; applying the entire display substrate with wetting fluid, wherein the wetting fluid can be fused with alignment liquid; transferring the alignment liquid on the display substrate applied with the wetting fluid by a transfer roller; and curing the alignment liquid to form an alignment layer. The manufacturing method is used for producing the alignment layer on the display substrate.

Abstract: The present disclosure provides a display substrate and a display device. The display substrate includes a subpixel, a black matrix arranged around the subpixel, and a spacer arranged on the black matrix. At least a portion of the black matrix includes a primary region and a secondary region, one of which is arranged between two adjacent subpixels in an alignment rubbing direction. The spacer is arranged on the primary region, and an alignment rubbing shadow is shielded by the primary region.

Abstract: A black matrix, a display substrate, a display screen and a display device are provided. The black matrix includes a plurality of openings of a mesh, and shielding regions configured to shield each main support column provided on the black matrix. When each main support column moves, a vertical projection of a movable area of the main support column on the black matrix falls within the shielding region corresponding to the main support column.

Abstract: A method of validating card numbers is described. A card number input by a user using a terminal device is obtained. It is judged whether an organization identity obtained from the card number is an identity of an organization that issues cards. A determination is made that the card number is invalid if the organization identity obtained from the card number is not an identity of an organization that issues cards.

Abstract: A server with processor(s) and memory receives a transaction request from a first device to perform a transaction with an account and determines a security level for the transaction. When the security level satisfies predetermined criterion, the server: instructs the first device to suspend the transaction and to display a first interface indicating the suspended transaction; and sends a confirmation request, to a second device associated with the account, for voice verification of the transaction. The server receives voice verification information from the second device that includes audio data provided by a user of the second device and determines whether the voice verification information matches stored account verification data corresponding to the account. When there is a match, the server: processes the transaction; and instructs the first device to complete the transaction and to replace display of the first interface with a second interface indicating the completed transaction.
