Title:
MACHINE LEARNING PROGRAM, MACHINE LEARNING METHOD, AND INFERENCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/064660
Kind Code:
A1
Abstract:
A machine learning program according to an embodiment of the present invention causes a computer to execute a process for generating a trained model and a process for generating a third model. The process for generating the trained model generates the trained model by, in response to the input of training data including a set of a first image and a second image, and a first label indicating which of the first image and the second image shows greater movement of the facial expression muscles of a subject, executing machine learning using a first model based on the first label, a first output value obtained by inputting the first image to the first model, and a second output value obtained by inputting the second image to a second model that shares a parameter with the first model. The process for generating the third model generates the third model through machine learning based on a third output value obtained by inputting a third image to the trained model and a second label indicating the intensity or presence/absence of movement of the facial expression muscles of the subject included in the third image.
