Patent Images

1. A computer-readable medium storing a learning-model generating program causing a computer to execute a process, the process comprising:

  • extracting a plurality of feature values from an image for learning that is an image whose identification information items are already known, the identification information items representing the content of the image;

    generating learning models by using a plurality of binary classifiers, the learning models being models for classifying the plurality of feature values and associating the identification information items and the plurality of feature values with each other; and

    optimizing the learning models for each of the identification information items by using a formula to obtain conditional probabilities, the formula being approximated with a sigmoid function, and optimizing parameters of the sigmoid function so that the estimation accuracy of the identification information items is increased.
