  • Patent number: 11836249
    Abstract: Aspects of the present disclosure involve systems, methods, devices, and the like for generating an adversarially resistant model. In one embodiment, a novel architecture is presented that enables the identification of an image that has been adversarially attacked. The system and method used in the identification introduce the use of a denoising module used to reconstruct the original image from the modified image received. Then, further to the reconstruction, an adversarially trained model is used to make a prediction using at least a determination of a loss that may exist between the original image and the denoised image.

  • Publication number: 20230260302
    Abstract: Methods and systems are presented for extracting categorizable information from an image using a graph that models data within the image. Upon receiving an image, a data extraction system identifies characters in the image. The data extraction system then generates bounding boxes that enclose adjacent characters that are related to each other in the image. The data extraction system also creates connections between the bounding boxes based on locations of the bounding boxes. A graph is generated based on the bounding boxes and the connections such that the graph can accurately represent the data in the image. The graph is provided to a graph neural network that is configured to analyze the graph and produce an output. The data extraction system may categorize the data in the image based on the output.
