Abstract: Computer-implemented methods, apparatuses, and computer-readable media for model training and text processing are disclosed. In an example, an original text, a positive sample, and a negative sample are obtained. The positive sample and the negative sample are rewritten texts of the original text. A first, second, and third distribution parameter corresponding to the original text, the positive sample, and the negative sample, respectively, are determined by using an encoder. The first, second, and third distribution parameter are used to describe a first, second, and third semantic distribution, respectively. A model parameter of the encoder is optimized by using a loss function based on the first, second, and third distribution parameter. The loss function includes a first term that is used to constrain a degree of similarity between the first and second semantic distribution to be higher than a degree of similarity between the first and the third semantic distribution.

Abstract: A network device receives a packet that includes a plurality of header fields. The packet is parsed to sequentially obtain the plurality of header fields. One or more header fields not yet available at the network device are predicted based on one or more header fields that are available at the network device. A network processing decision is generated for the packet based on the predicted one or more header fields and the one or more header fields that are available at the network device.

Abstract: A network device receives a packet that includes a plurality of sets of fields. Sets of fields of the packet are parsed and the field sets are evaluated as soon as they are available to determine whether a processing decision can be made on the packet. Additional field sets may be parsed from the packet and obtained in parallel with determining whether a processing decision can be made, but once it is determined that a processing decision can be made, the evaluating of field sets is terminated such that any further field sets of the packet are ignored for purposes of making a processing decision for the packet.

Abstract: An electronic device may be provided with integrated circuits and electrical components such as capacitors that are soldered to printed circuit boards. Liquid polymer adhesive such as encapsulant and underfill materials may be deposited on the printed circuit. Electrical components such as capacitors may be coated with the encapsulant. The underfill may be deposited adjacent to an integrated circuit, so that the underfill wicks into a gap between the integrated circuit and the printed circuit board. The encapsulant may be more viscous than the underfill and may therefore prevent the flowing underfill from reaching the electrical components. Some of the encapsulant may be located between the electrical components and the printed circuit board. The encapsulant can be cured to form an elastomeric material covering the electrical components that helps damp vibrations. The elastomeric material may be less stiff than the underfill.

Abstract: Presented herein are techniques to achieve ultra low latency determination of processing decisions for packets in a network device. A packet is received at a port of a network device. A processing decision is determined in a first processing decision path based on content of the packet and one or more network policies. A processing decision is determined in a second processing decision path, in parallel with the first processing path, by accessing a table storing processing decisions. The second processing decision path can output a processing decision faster than the first processing decision path for packets that match one or more particular packet flow parameters contained in the table. A processing decision determined by the second processing decision path, if one can be made, is used, and otherwise a processing decision determined by the first processing decision path is used.

Abstract: A multi-destination expansion table is stored that comprises a first database containing data representing all nodes in a singly linked list that is a superset of nodes for a plurality of multi-destination groups and a second database storing data representing multi-destination group specific arcs across one or more nodes. The singly linked list is traversed to determine how to replicate a packet for a particular multi-destination group. The packet is replicated based on interface data stored in the first database associated with the current node address. When a match is found in the second database, a next node address is determined from the second database. When a match is not found in the second database, a next node address determined from accessing the first database. Traversing of the singly linked list is terminated when the next node address is determined to be invalid or null.
