Abstract: The disclosure provides a target detection method and apparatus, a model training method and apparatus, a device, and a storage medium. The target detection method includes: obtaining a first image; obtaining a second image corresponding to the first image, the second image belonging to a second domain; and obtaining a detection result corresponding to the second image through a cross-domain image detection model, the detection result including target localization information and target class information of a target object, the cross-domain image detection model including a first network model configured to convert an image from a first domain into an image in the second domain, and the second network model configured to perform region localization on the image in the second domain.

Abstract: It is determined whether a short message locked. The short message is in a locked short message storage area if it is determined that the short message locked. A locked short message session containing the short message is displayed in a short message display interface. The short message display interface displays the locked short message session and an unlocked short message session containing another short message stored in an unlocked short message storage area. The locked short message storage area is different from the unlocked short message storage area.

Abstract: The present disclosure provides an information pushing method, server, and storage medium. The method includes: obtaining first behavioral data of a user account, the first behavioral data comprising a first quantity of active behaviors and a first quantity of passive behaviors of the user account; calculating a first activity level score of the user account according to the first behavioral data; detecting whether the first activity level score of the user account is less than a preset threshold; if the first activity level score of the user account is less than the preset threshold, calculating a friend activity level score of each friend account in a friend list of the user account; and pushing related information of a target friend account whose friend activity level score meets a preset condition to the user account.

Abstract: This application discloses a virtual machine (VM) hot migration method, an apparatus, and a storage medium. A method for virtual machine (VM) hot migration is described. Processing circuitry of a first host machine identifies that a memory block in a storage device of the first host machine is allocated to a virtual machine to migrate. Further, the processing circuitry determines whether the memory block is data-containing. When the memory block is data-containing, interface circuitry of the first host machine sends data in the memory block to a second host machine. When the memory block is not data-containing, the memory block is skipped for migration.

Abstract: A networking activity interactive system includes: a creating module for creating networking activity contents; an interactive module for receiving requests for participating the networking activity and participant data submitted by a user, to ensure only participant data in conformity with the networking activity contents is added to the participant user group of the networking activity, and the user is added to the participant user group; a database for storing the networking activity contents, the participant user group of the networking activity, and the participant reply content volume; a presenting module for presenting the networking activity content and the participant reply content volume of the networking activity. Furthermore, a method, a client terminal and a server for networking activity interactive are also provided. The present interactive system and method hereof, ensure that the participant data submitted by the user is in conformity with the created networking activity contents.

Abstract: The present application discloses methods and devices for intercommunication between mobile terminals based on digital networks. A first mobile terminal may connect to a uniquely identified server based on a first terminal identifier corresponding to the first mobile terminal. In addition, the first mobile terminal may connect to the server through a default connection setup embedded in the first terminal identifier. By acquiring terminal identifiers corresponding to interacting mobile terminals, the first mobile terminal may establish communication channels with the interacting mobile terminals. After adding the terminal identifiers of the interacting mobile terminals to the contact lists of the first mobile terminal, different regions of the first mobile terminal may be designated to the interacting mobile terminals so that the regions may display the status of communication and serve as interfaces to control receiving, playing, recording, and transmitting digital contents encoding voice messages.

Abstract: The present invention provides a network search system, including: a search initiating client, configured to initiate a search request to a resource search server, and acquire network resource according to a resource feature information index returned by a resource search server; the resource search server, configured to acquire a search response client corresponding to the search initiating client according to a corresponding relation between the search response client and the search initiating client, search a resource index server corresponding to the search response client according to the search request, and return the resource feature information index to the search initiating client; the resource index server, configured to store the resource feature information index reported by the search response client. A network search method is also disclosed. By use of the present invention, it is possible to improve the instant performance of network search and the individuation of the search result.
