Combined light and heavy models for image filtering

A system for demographic determination using image recognition, comprising:

• a memory, wherein a pre-trained lightweight neural network model and a pre-trained heavyweight neural network model are stored in the memory;
• one or more processors configured to execute the pre-trained lightweight neural network model and the pre-trained heavyweight neural network model, wherein the pre-trained heavyweight neural network model has above about one million trainable parameters and the pre-trained lightweight neural network model has a number of trainable parameters below one tenth the heavyweight model, and compare a confidence value generated by the pre-trained lightweight neural network model to a threshold value, wherein the one or more processors are configured to execute the pre-trained heavyweight neural network model if the pre-trained lightweight neural network model is sufficiently accurate;
• and
• a user interface configured to display demographic data to a user, wherein the user modifies store inventory based on the demographic data.

A non-transitory computer readable storage medium comprising a computer readable program for demographic determination using image recognition, wherein the computer readable program when executed on a computer causes the computer to perform:

• analyzing an image with a pre-trained lightweight neural network model, where the lightweight neural network model generates a confidence value;
• comparing the confidence value to a threshold value to determine if the pre-trained lightweight neural network model is sufficiently accurate;
• analyzing the image with a pre-trained heavyweight neural network model for the confidence value below the threshold value, wherein the pre-trained heavyweight neural network model has above about one million trainable parameters and the pre-trained lightweight neural network model has a number of trainable parameters below one tenth the heavyweight model;
• and
• displaying demographic data to a user on a user interface, wherein the user modifies store inventory based on the demographic data.
