  • Patent number: 10977449
    Abstract: This disclosure relates to language processing using a neural network. In one aspect, a method includes performing, at an embedding layer of a neural network, embedding processing on a current input to obtain feature vectors. The neural network includes at least one transformer layer that includes a first transformer layer including an attention layer and a pooling layer. A quantity P of input vectors are obtained at the attention layer. P intermediate vectors are determined based on the input vectors. For each input vector of the P input vectors, a respective intermediate vector is obtained using the corresponding input vector as a center and based on correlation values calculated between the input vector and each other input vector in a predetermined attention window range. The P intermediate vectors are combined to form a quantity Q of output vectors. Output vectors are generated as a feature representation of the current input.

  • Publication number: 20200045770
    Abstract: The present disclosure relates to implementing policy control. In one example communication system, a core network exposes a service policy to an application server, and the application server authorizes user equipment with the service policy. Before accessing a service provided by the application server, the user equipment pushes, to the core network, the service policy that needs to be used to access the application server. A core network device performs policy control such as charging, QoS, routing, gating control, or redirection on a service flow or a data packet between the user equipment and the application server according to the service policy pushed by the user equipment.
