  • Patent number: 12250149
    Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.

  • Patent number: 11915500
    Abstract: A system uses a neural network based model to perform scene text recognition. The system achieves high accuracy of prediction of text from scenes based on a neural network architecture that uses double attention mechanism. The neural network based model includes a convolutional neural network component that outputs a set of visual features and an attention extractor neural network component that determines attention scores based on the visual features. The visual features and the attention scores are combined to generate mixed features that are provided as input to a character recognizer component that determines a second attention score and recognizes the characters based on the second attention score. The system trains the neural network based model by adjusting the neural network parameters to minimize a multi-class gradient harmonizing mechanism (GHM) loss. The multi-class GHM loss varies based on a level of difficulty of the sample.

  • Publication number: 20230236733
    Abstract: The present invention provides a data loading method. The method comprises: reading data from an initial address in a memory; obtaining a frame header identifier, loading a valid data segment comprising the frame header identifier; verifying the valid data segment; when it is determined that the verification is successful, sending at least part of information within the valid data segment to a cache unit; updating a register according to at least part of the information by the cache unit. Using a specific frame header identifier, loading data in the memory starts only from the specific frame header identifier, which skips the data before the frame header identifier and avoids loading invalid data in the cache unit, thus saving time, preventing lengthy program, and being more scientific and convenient.
