1. A data category identification method based on a deep neural network for an apparatus comprising a memory and a processor, the method comprising:

  • establishing an initial deep neural network;

    generating a linear category analysis function after data category information is added to a locally saved initial linear category analysis function in the memory, the linear category analysis function being generated from an input training sample vector set;

    generating an optimization function of the initial deep neural network from a locally saved unsupervised auto-encoding model optimization function in the memory and the linear category analysis function;

    acquiring a parameter of the initial deep neural network from the optimization function of the initial deep neural network;

    generating the deep neural network from a locally saved classification neural network in the memory, the initial deep neural network, and the parameter of the initial deep neural network, the deep neural network having a multi-layer network structure comprising at least an input layer and an output layer;

    receiving to-be-identified data from a user device and inputting the to-be-identified data to the input layer of the deep neural network, the to-be-identified data comprising image information or text information;

    applying the deep neural network to the image information or the text information comprising the to-be-identified data to obtain information for a category of the to-be-identified data;

    determining information for the category of the to-be-identified data in the image information or the text information in response to applying the deep neural network to the image information or the text information; and

    outputting the information for the category by the output layer of the deep neural network to permit categorization of the to-be-identified data, the linear category analysis function ζ
