Abstract: Embodiments of this application provide a method of distributing information from an allocator terminal to a client terminal over a communication network. Information allocation data in an information allocation system is collected by processing circuitry. The information allocation system is configured to allocate the information to a client terminal. The information allocation data includes data associated with a process of allocating the information. Data of actual effect and estimated effect of allocating the information is calculated according to the information allocation data. An allocation instruction is generated according to a comparison between the actual effect data and the corresponding estimated effect data. The allocation instruction is provided to the allocator terminal.

Abstract: The present disclosure relates to a method and system for monitoring on route transportations. The method includes obtaining a driving route of a target vehicle; obtaining a reference position on the driving route away from a first current position of the target vehicle; determining a second current position of the target vehicle after a reference time; determining a distance between the second current position and the reference position is greater than a preset distance; and sending a signal to a target terminal indicating that the target vehicle is off-route.

Abstract: A method for generating a targeted label is provided. An official account in a social network platform is determined by processing circuitry of an apparatus. A plurality of user accounts in the social network platform that follows the official account of the determined provider is determined. Each of the plurality of user accounts has a corresponding user label that indicates a user attribute of a user associated with the respective user account. The plurality of user accounts is added to a set of targeted user accounts. The targeted label for the recommendation information is determined according to the user labels of the plurality of user accounts. Subsequently a set of target user accounts in the social network platform is determined according to the determined targeted label, and the recommendation information is sent to user clients of the user account included in the set of target user accounts.

Abstract: A method and device for training a tree model based on a dataset are disclosed. The dataset comprises m pieces of sample data and m sample labels, each sample data comprises n features, the features and feature values in the dataset are ciphertexts, the method comprises: generating, for the dataset, candidate splits based on ciphertexts; partitioning, for each candidate split, the dataset into a left and right subset based on ciphertexts; calculating a partition coefficient of each candidate split based on the left and right subset obtained through partition for each candidate split; determining a feature in a target candidate split as an optimal feature, determining a threshold in the target candidate split as an optimal splitting value, the optimal feature and the optimal splitting value are ciphertexts; assigning the dataset to two child nodes of the current node based on the optimal feature and the optimal splitting value.

Abstract: An image classification method based on reliable weighted optimal transport (RWOT) includes: preprocessing data in a source domain, so that a deep neural network fits a sample image in the source domain to obtain a sample label; performing image labeling to add a pseudo label to a data sample in a target domain; performing node pairing to pair associated images in the source domain and the target domain; and performing automatic analysis by using a feature extractor and an adaptive discriminator, to perform image classification. The present disclosure proposes a subspace reliability method for dynamically measuring a difference between the source domain and the target domain based on spatial prototypical information and an intra-domain structure. This method can be used as a preprocessing step of an existing domain adaptation technology, and greatly improves efficiency.

Abstract: The disclosure relates to techniques for scan preparation in a medical imaging system. The technique includes triggering a 3D camera acquiring a 2D color and depth image of a patient when a patient bed is at an origin position, inputting the image into a pre-trained first body information model to obtain position information of multiple body feature site points, and calculating position information of multiple candidate scanning regions in the patient bed coordinate system. The technique further includes providing the position information of the multiple candidate scanning regions to a medical imaging application apparatus, so that the medical imaging application apparatus determines position information of a current scanning region in the patient bed coordinate system and controls the patient bed to move the current scanning region to a scanning center of a medical imaging device according to the position of the patient bed relative to the scanning center.

Abstract: A modularised charging vehicle, aiming at solving the problem of repeated development caused by the fact that an existing charging vehicle needs to configure separate charging piles for various specifications of electric automobiles. A charging vehicle comprises a main controller and at least two charging and discharging modules, wherein the charging and discharging modules comprise a charging input end, a battery pack, a DC/DC converter and a charging output end. The battery pack is connected to the charging input end and the DC/DC converter. The DC/DC converter is connected to the charging output end. The charging and discharging modules are connected in parallel to each other, and are combined into one path for inputting and are combined into one path for outputting. The controller can control the charging and discharging modules to store and release electric energy, so as to achieve an input or output function of different power.
