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.

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.

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 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.
