Abstract: A neural network training method in the artificial intelligence field includes: inputting training data into a neural network; determining a first input space of a second target layer in the neural network based on a first output space of a first target layer in the neural network; and inputting a feature vector in the first input space into the second target layer, where a capability of fitting random noise by the neural network when the feature vector in the first input space is input into the second target layer is lower than a capability of fitting the random noise by using an output space that is in the neural network and that exists when a feature vector in the first output space is input into the second target layer. This application helps avoid an overfitting phenomenon that occurs when the neural network processes an image, text, or speech.

Abstract: Embodiments of the present invention provide an information presentation method and device. The method includes: receiving, by a mobile terminal, first information provided by a communications network; determining, by the mobile terminal, a presentation priority of the first information in a current situation of a user; and sending the first information to a wearable device when the presentation priority of the first information in the current situation is greater than or equal to a second preset value, so that the wearable device presents the first information to the user. According to the information presentation method and device provided by the embodiments of the present invention, information can be presented according to a scene of a user, so that a presentation effect is improved, and interference of information unrelated to a current situation with the user is reduced.

Abstract: In a method for selecting pictures from a sequence of pictures of an object in motion, a computerized user device determines, for each picture in the sequence of pictures, a value of a motion feature of the object. Based on analyzing the values of the motion feature of the pictures in the sequence, the device identifies a first subset of pictures from the pictures in the sequence. The device then selects, based on a second selection criterion, a second subset of pictures from the first subset of pictures. The pictures in the second subset are displayed to a user for further selection.

Abstract: Sending a search request includes: during a running procedure of a search engine client, generating a forged search request, where the forged search request carries a forged search word; and sending the forged search request to the search engine server. The forged search request is sent to the search engine server, to serve as a factor interfering with an analysis of a user behavior by the search engine server based on a true search request, to prevent the search engine server from analyzing the user behavior based on a search word entered by a user, thereby improving user experience.

Abstract: Example prediction methods and apparatus are described. One example includes sending a first model parameter and a second model parameter by a server to a plurality of terminals. The first model parameter and the second model parameter are adapted to a prediction model of the terminal. The server receives a first prediction loss sent by at least one of the plurality of terminals. A first prediction loss sent by each of the at least one terminal is calculated by the terminal based on the prediction model that uses the first model parameter and the second model parameter. The server updates the first model parameter based on the first prediction loss sent by the at least one terminal to obtain an updated first model parameter. The server updates the second model parameter based on the first prediction loss sent by the at least one terminal to obtain an updated second model parameter.

Abstract: This application relates to the field of artificial intelligence. A dialog interaction method, a graphical user interface, a terminal device, and a network device are provided in this application. The disclosed terminal device displays a dialog view in a first region of a target dialog user interface, and displays a conceptual view in a second region of the target dialog user interface. The dialog view is used to display dialog data of the target dialog. The conceptual view is used to display a knowledge subgraph corresponding to the target dialog. The knowledge subgraph includes a plurality of semantic entities and a semantic relationship between semantic entities in the plurality of semantic entities. The plurality of semantic entities include a first semantic entity. The first semantic entity is a semantic entity existing in the dialog data. The technical solution can improve dialog interaction experience of a user.
