Abstract: Embodiments of this specification provide methods and apparatuses for performing model ownership verification based on an exogenous feature. An implementation of the methods includes: selecting initial samples from an initial sample set to form a selected sample set, processing sample data of the initial samples to obtain transform samples that form a transform sample set, training a meta-classifier based on a target model, an auxiliary model, and the transform sample set, inputting data associated with a suspicious model into the meta-classifier, and determining, based on an output result of the meta-classifier, whether the suspicious model is stolen from a deployment model, wherein the deployment model has feature knowledge of the exogenous feature.

Abstract: A drying air duct, a clothing treatment device and a method for cleaning a drying air duct are provided. The drying air duct includes a condensing section air duct, a heating section air duct and a fan; the fan is provided at a connection position of the condensing section air duct and the heating section air duct, a cleaning device is provided in the condensing section air duct, the cleaning device is provided at an end of the condensing section air duct adjacent to the fan and is capable of cleaning a side of the condensing section air duct away from the fan. The drying air duct can effectively clean the pipe sudden expansion area of the condensing section air duct, preventing the accumulation of soft flocks in the condensing section air duct.

Abstract: A center tube core and a cosmetic packaging tube that contains the center tube core are provided. The center tube core comprises a prong, a spiral rotatably sleeved on the prong, and a bead slidably mounted in the prong so as to carry a product. The side wall of the prong is provided with a slide slot that extends axially, the outer wall of the bead is provided with a slide block that extends radially out from the slide slot, and the inner wall of the spiral is provided with a feeding thread that acts on the slide block. The prong, the bead and the spiral are all made using a metal material.

Abstract: A card use system includes a first client configured to send a card use request including card information of a card, and display a payment code including a first resource account number corresponding to the first client; a second client configured to send a payment request to transfer a first quantity of resources from the first resource account number to a second resource account number corresponding to the second client; a card server configured to validate the card according to the card information; and in response to successfully validating the card, send a confirmation indication to the payment server; and a payment server configured to, in response to receiving the confirmation indication from the card server, transfer a second quantity of resources in the first resource account number corresponding to the first client to the second resource account number corresponding to the second client.

Abstract: Embodiments include information processing methods, a server, a terminal, and non-transitory computer-readable storage mediums. One information processing method includes receiving a request for electronic information. The request for the electronic information is sent by a first user logged into a first terminal. The method includes recommending and sharing at least one piece of recommended information, which corresponds to the electronic information, to at least one second user according to a recommendation and/or sharing rule associated with the electronic information. The at least one second user is associated with the first user. The method further includes, when the at least one second user logs into a second terminal and performs a function based on the at least one piece of recommended information, sending at least one piece of content information to a database accessible by the first user according to the at least one piece of recommended information.

Abstract: A lipstick tube cartridge core comprising a ball (1), a fork (2), a spiral (3), and a cartridge (4). The spiral (3) and the cartridge (4) are provided therebetween with a keyway structure (33 and 43) arranged in the axial direction and an engaging ring (31 and 42) and engaging groove (32 and 41) structure arranged in the circumferential direction. As the spiral (3) and the cartridge (4) are provided therebetween with the keyway structure (33) arranged in the axial direction and the engaging ring (31 and 42) and engaging groove (32 and 41) structure arranged in the circumferential direction, retention of the spiral (3) and of the cartridge (4) is implemented without using a glue, thus preventing a scenario in which a cosmetic paste is contaminated by the glue.
