Abstract: A web member for a truss with high sectional strength and an assembled truss is formed by transforming ends of an M-shaped web member into two double-layer connecting plates for connection through end transformation, grooving and drilling while steel consumption is not increased; and connection joints of a conventional truss are usually controlled by bearing capacities of bolts of which the sectional strength is insufficient, the thickness of bolt connections on ends of the web member is increased by flattening, and thus, pressure bearing capacities of the bolts will be greatly improved. The truss provided by the present utility model is a fully-bolted truss, connections of two adjacent web members and chord members are connected to intersection points of center-of-gravity lines of the web members and the chord members.

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.
