INFORMATION PROCESSING SYSTEM AND INFERENCE METHOD

An information processing system includes an edge computer that implements a preceding stage of a learning model, and a cloud computer that implements a subsequent stage of the learning model, wherein the edge computer includes a first processor configured to calculate a first feature amount by inputting a first image to the preceding stage, identify an area of interest in the first image based on the first feature amount, generate a second image obtained by masking the area of interest in the first image, calculate a second feature amount by inputting the second image to the preceding stage, and transmit the second feature amount to the cloud computer, and the cloud computer includes a second processor configured to infer an object included in the second image by inputting the second feature amount to the subsequent stage.
