Abstract: Example facial image processing methods and apparatus are described. One example method includes obtaining a low-quality facial image and a first cluster label. A first target facial feature and a second target facial feature of the low-quality facial image are extracted. Each of P third target facial features is divided into R categories of first facial sub-features according to the first cluster label, where the P third target facial features are an output of a target convolutional neural network module of a face generator. An input that is of the target convolutional neural network module and that corresponds to the P third target facial features is obtained based on the first target facial feature. The first facial sub-features that are obtained through division are combined to obtain a first combined facial feature.

Abstract: A method and an apparatus for sending a TCP data packet and a system. The method includes: obtaining a first round-trip time of sending a TCP data packet in a network, and determining a second round-trip time; if the first round-trip time is longer than the second round-trip time, using a congestion window determined according to a first algorithm as a first congestion window; otherwise, using a congestion window determined according to a second algorithm as the first congestion window; and sending the TCP data packet by using the first congestion window. In the technical solution disclosed in the present invention, a current congestion window that exists when a first round-trip time is obtained grows to a first congestion window at one go, so that a requirement of a service for a throughput can be better met, and a network bandwidth can be utilized more effectively.

Abstract: This application provides a federated learning method and apparatus. The method includes: A first server receives a request message sent by at least one first client. The first server sends a training configuration parameter and a global model to the at least one first client. The first server receives first model update parameters separately fed back by the at least one first client. The first server aggregates the first model update parameters, to obtain first aggregation information in a current round of iteration. The first server obtains second aggregation information sent by the second server. The first server updates, based on the first aggregation information and the second aggregation information, the global model stored on the first server.

Abstract: A data transmission method includes determining that a first network address segment overlaps with a second network address segment, and creating at least two subnets on a virtual private cloud (VPC). The first network address segment is a network address segment of a subnet in which a target server is located, and configured to run on the VPC. The first network address segment belongs to a network address segment of the VPC. The second network address segment is a network address segment of a subnet in which a first electronic device is located. A network address segment of one of the at least two subnets on the VPC does not overlap with the first or second network address segment. Network interfaces in the at least two subnets are configured to sequentially forward a data packet being transmitted between the target server and the first electronic device at least two times.

Abstract: An image processing apparatus and a method are provided. The apparatus comprises a plurality of processing modules configured to operate in series to refine a raw image captured by a camera, the modules comprising a first module and a second module, each of which independently implements a respective trained artificial intelligence model, wherein: the first module implements an image transformation operation that performs an operation from the set comprising: (i) an essentially pixel-level operation that increases sharpness of an image input to the module, (ii) an essentially pixel-level operation that decreases sharpness of an image input to the module, (iii) an essentially pixel-block-level operation on an image input to the module; and the second module as a whole implements a different operation from the said set.
