Information processing system and inference method

An inference method, comprising:

• calculating, by a first computer, a first feature amount by inputting a first image to a top layer among the plurality of layers of the preceding stage;
• identifying, by the first computer, an area of interest in the first image based on the first feature amount;
• generating, by the first computer, a second image obtained by masking the area of interest in the first image;
• calculating, by the first computer, a second feature amount by inputting the second image to the top layer among the plurality of layers of the preceding stage;
• transmitting, by the first computer, the second feature amount to the cloud computer;
• and
• inferring, by a second computer different from the first computer, an object included in the second image by inputting the second feature amount to a top layer among the plurality of layers of the subsequent stage.

A non-transitory computer-readable recording medium storing a program for causing a first computer and a second computer different from the first computer to execute a process, the process comprising:

• calculating, by the first computer, a first feature amount by inputting a first image to a top layer among the plurality of layers of the preceding stage;
• identifying, by the first computer, an area of interest in the first image based on the first feature amount;
• generating, by the first computer, a second image obtained by masking the area of interest in the first image;
• calculating, by the first computer, a second feature amount by inputting the second image to the top layer among the plurality of layers of the preceding stage;
• transmitting, by the first computer, the second feature amount to the cloud computer;
• and
• inferring, by the second computer, an object included in the second image by inputting the second feature amount to a top layer among the plurality of layers of the subsequent stage.
