Abstract: An information processing apparatus (2000) classifies each event that occurred in a target apparatus to be determined (10) either as an event (event of a first class) that also occurs in a standard apparatus (20) or as an event (event of a second class) that does not occur in the standard apparatus (20). Herein, a first model used for a determination with respect to an event that also occurs in the standard apparatus (20) and a second model used for a determination with respect to an event that does not occur in the standard apparatus (20) are used as models for determining whether an event that occurs in a target apparatus to be determined (10) is a target for warning. The information processing apparatus (2000) performs learning of the first model using an event of the first class. Further, the information processing apparatus (2000) performs learning of the second model using an event of the second class.

Abstract: A learning model is trained so that a signal state can be estimated with high accuracy even in a case where a constellation on a complex plane is rotated. A learning apparatus (1) includes: an acquisition section (11) that acquires a constellation of a known state optical signal transmitted through optical fiber; a generation section (12) that generates a corrected constellation obtained by rotating the constellation on a complex plane; and a learning section (13) that uses the constellation and the corrected constellation to train a learning model.

Abstract: An information processing device 1X mainly includes a selection means 32X and an inference means 35X. The selection means 32X is configured to select, based on one or more geographical center points according to a movement history of an inference target device, one or more adaptive inference models to be used from inference models generated on an area-by-area basis, the inference models making inferences of a state of the inference target device. The inference means 35X is configured to make an inference of the state of the inference target device based on inference results of the adaptive inference models which use data acquired by the inference target device.
