Abstract: The purpose of the present invention is to provide a technology which assists a verifying party in ascertaining an anomaly in an event of which notification has been made. Provided is an assistance device, comprising: an acquisition unit which acquires as an associated event, from among events which take place among a plurality of elements, and with respect to elements which have been associated with an event which has been detected as an anomalous event, an event other than the anomalous event which has been associated with the elements; and a generating unit which, on the basis of the anomalous event and the associated event, generates a relational graph in which the elements are vertices, the relations among the elements are edges, the anomalous event and the associated event are respectively represented, and the associated event is displayed in a display screen in a different manner from the manner in which the anomalous event is displayed.

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: 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.

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.
