Patent Images

1. A non-transitory computer readable recording medium storing a program that causes a computer to execute:

  • receiving data;

    receiving supervision; and

    performing artificial neural network processing to determine a gender of a poster of an image from image content of the image, the image being read from the received data,wherein performing the artificial neural network processing includesprocessing a main task with a first sub-network including one or more layers, the main task corresponding to gender estimation, the first sub-network configured to extract a first feature amount which is a feature amount of the gender,processing a sub-task with a second sub-network including one or more layers, the sub-task corresponding to content recognition, the second sub-network configured to extract a second feature amount which is a feature amount of the image content, andperforming processing not included in any of the main task and the sub-task with a third sub-network including one or more layers, the third sub-network not sharing a layer with any of the first sub-network and the second sub-network, the third sub-network configured to extract a third feature amount that is an output result from the image, whereinperforming the processing not included in any of the main task and the sub-task includes outputting a value same as an input feature amount to a plurality of layers of the first sub-network and the second sub-network, andprocessing the main task includes coupling inputs from the plurality of layers of the first sub-network and the second sub-network and outputting a result, wherein the coupling includes coupling the feature amount of the gender and the feature amount of the image content by performing processing of concatenating the feature amount of the gender and the feature amount of the image content, or processing of calculating with respect to the plurality of layers of the first sub-network and the second sub-network for each element of the received feature amount of the gender and the received feature amount of the image content so as to integrate the feature amount of the gender and the feature amount of the image content, and outputting the result.
