Abstract: The diagnosis device specifies a progression degree relating to a first information processing device for output information output by a first detection device at a first timing with respect to the first information processing device, based on device information indicates a progression degree that represents a degree to which the information processing device is abnormal with respect to the information processing device, determines whether or not information in which a first detection device identifier of the first detection device and the specified progression degree are associated with each other is included in progression-degree information in which a detection device identifier capable of identifying a detection device and the progression degree are associated with each other; and calculates the progression degree relating to the first information processing device according to the specified progression degree when the information is determined to be included in the progression-degree information.

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: To enable a user to easily recognize temporal order of elements included in a retrieval sentence, a retrieval sentence utilization device 10 includes: a retrieval sentence division unit 11 for dividing a retrieval sentence into a plurality of retrieval contents each of which includes an event; and a directed graph generation unit 12 for generating, from each of the retrieval contents, a subtree in which the event is an edge and a source of the event and an object of the event are nodes, and integrating a plurality of subtrees generated from the retrieval contents to generate a directed graph, wherein the directed graph generation unit 12 places the plurality of subtrees in the directed graph according to occurrence order of events corresponding to the plurality of subtrees.

Abstract: The present invention provides an information processing system for more appropriately classifying elements that constitute an information processing device or the like. This information processing system is provided with: a means that, on the basis of information indicating the relationship between a plurality of elements that constitute a system, acquires, for first elements to be classified, a set of second elements capable of arriving at the first elements via a relationship of arbitrary numbers; and a means that, on the basis of the set corresponding to the first elements, classifies each of the first elements in any of a plurality of roles.
