After assembly, one end of the resisting member abuts against the sliding member, and the other end of the resisting member extends out of a bottom wall surface of the fixing slot.

Abstract: A rotary connection structure includes a first external connection assembly and a rotation damping structure. The first external connection assembly is for external connection with a first photography device. The rotation damping structure includes a mounting member, a fastening member, and a connecting member. One end of the fastening member extends through the connecting member to fix and connect to the mounting member. The connecting member is rotatable, in a damped manner, about the fastening member. The connecting member is connected to the first external connection assembly. The first external connection assembly can be a clamp assembly. The mounting member is for connection with a second photography device. The second photography device can be a handgrip, and the handgrip is fixedly connected to the mounting member. The rotary connection structure proposed in the present invention realizes rotation of the first photography device and the second photography device.

Abstract: The present disclosure discloses a composite bearing. The composite bearing includes a housing, two locking assemblies, a transmission assembly, and an unlocking assembly. The housing is defined with a mounting hole. The two locking assemblies are rotatably arranged in the mounting hole in sequence, both two locking assemblies are defined with a through hole configured to mount an external shaft. A side wall of the locking assemblies is provided with rolling members located between an inner wall of the mounting hole and the external shaft. The transmission assembly is connected to the two locking assemblies respectively so that the two locking assemblies may clamp the external shaft in the through hole. The unlocking assembly is connected to the two locking assemblies respectively to drive the two locking assemblies to release the external shaft. In the present disclosure makes it convenient for users to quickly adjust the desired shooting angle.

Abstract: A session-based recommendation method and device according to one or more embodiments of this disclosure are provided, which use a pre-trained recommendation model to perform item recommend. The method includes following contents: a directed session graph is constructed according to a session to be predicted; the directed session graph is then input into a gated graph neural network which outputs the item embedding vector; a user's dynamic preference is determined according to a user's current preference and a first long-term preference, the current preference is an item embedding vector of a last item in the session and the first long-term preference is determined according to the item embedding vector and an importance score of the item; a prediction score of a respective item is determined according to the dynamic preference and the item embedding vector; and a recommended item is output according to the prediction score of the respective item.

Abstract: The present disclosure provides an item recommendation method and system based on a user intention in a conversation session. In this method, a current conversation session is encoded by use of items of prior time sequence and the last item so as to generate an accurate conversation session representation which is then used to perform initial item prediction as a user intention. Afterwards, an intention-guided neighbor detector is used to locate an accurate neighbor conversation session. Finally, the current conversation session and the neighbor conversation session representations are combined adaptively by a gated mixed layer to generate the final item recommendation, so as to effectively improve the accuracy of item recommendation.
