1. A user identification system, comprising:

  • a processor configured to receive image data and run a neural network; and

    a memory configured to store the image data and the neural network, the neural network comprisingan image recognition subnetwork configured to analyze image data and generate shape data based on the image data;

    a generalist subnetwork configured to analyze the shape data and generate general category data based on the shape data;

    a specialist layer configured to compare the general category data with a characteristic to generate narrow category data; and

    a classifier layer including a plurality of nodes configured to represent a classification decision based on the narrow category data,wherein the image recognition subnetwork is directly coupled to the generalist network,wherein the generalist network is directly coupled to the specialist layer,wherein the specialist layer is directly coupled to the classifier layer, andwherein the neural network is a back propagation neural network including a plurality of layers.
