Abstract: Disclosed is a cloud-native application programming interface (API) recommendation method fusing data augmentation and contrastive learning. Service information is included on the basis of a service information double-graph structure, and a mutual attention mechanism is designed to compute an importance degree of each layer of information. A data optimization method for sequence information based on functional similarity and a computation method for similarity between services based on two parts of information are provided; on this basis, data of a service invocation sequence is augmented with the idea of contrastive learning to form an augmented sequence pair; a computational contrastive loss function is combined with a pair-wise recommendation loss function to optimize an overall model, thereby improving the effect of a service recommendation model; and according to a feature embedding representation result of a service, pair-wise recommendation scores are computed to complete service recommendation.

Abstract: The present invention relates to the video surveillance field, and discloses a trunk management method and apparatus for video surveillance systems. In the present invention, the connection priority of a surveillance equipment is the highest priority amon/between priorities of all clients, when multiple clients with different priorities access the same surveillance equipment. The connection priority of the surveillance equipment is set as the priority of a new client, if the new client accesses the surveillance equipment and the priority of the new client is higher than the connection priority of the surveillance equipment; the connection priority of the surveillance equipment is remained unchanged, if the priority of the new client is not higher than the connection priority of the surveillance equipment.
