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.

The composition is composed of ginseng powder of 250 meshes or more and ?-cyclodextrin, and the mass ratio of the ginseng powder to the ?-cyclodextrin is 1:0.05. Results show that when ?-cyclodextrin is used as a solid dispersant and added to the 1000-mesh ginseng powder at a mass ratio of 5%, the total dissolution amount is maximum; and furthermore, animal experiments (SD rats) show that the area under the plasma drug concentration-time curve (AUC0-48 h) after 48 h of ginseng powder ingestion is maximum, indicating that in-vivo bioavailability of the ginseng powder is the highest. The method of this application can effectively inhibit the aggregation of the ultra-finely pulverized 1000-mesh ginseng powder by adding the ?-cyclodextrin, thus significantly improving the total dissolution amount of ginsenoside.
