  • Publication number: 20240119268
    Abstract: This disclosure relates to the field of artificial intelligence, and discloses a data processing method. The method includes: obtaining a transformer model including a target network layer and a target module; and processing to-be-processed data by using the transformer model, to obtain a data processing result. The target module is configured to: perform a target operation on a feature map output at the target network layer, to obtain an operation result, and fuse the operation result and the feature map output, to obtain an updated feature map output. In this disclosure, the target module is inserted into the transformer model, and the operation result generated by the target module and an input are fused, so that information carried in a feature map output by the target network layer of the transformer model is increased.

  • Patent number: 8767688
    Abstract: A virtual network image system (VNIS) maintaining virtual counterparts for each of the entities in a real-world, physical wireless local area network (WLAN) to which the VNIS corresponds. The virtual counterparts operate in accordance with a communication protocol that corresponds to that of the WLAN and under the control of a VNIS manager component. The VNIS manager component predicts and optimizes operating configurations associated with the virtual counterparts, based on “what-if” analyses, to provide automation of various services relating to the operation of the physical WLAN.
