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

An information processing apparatus generates a graph that represents an action of a program. On the graph, an edge represents action contents of a process in an event. Further, two nodes connected by the edge respectively represent a subject and an object of the event. The information processing apparatus outputs the generated graph. Further, the information processing apparatus also alters the generated graph. When an index value of an event satisfies a first predetermined condition which index value is based on the number of occurrences or the frequency of occurrences of the event, the information processing apparatus alters the graph with respect to an edge representing the event.

Provided are a path control method, a wireless communication system, a path control device, and a non-transitory computer readable medium which are capable of securing efficient traffic accommodation, while maintaining communication quality. The path control method controls a communication path by selecting one path from among a plurality of path candidates with respect to a specific piece of traffic in a network constituted of a radio link provided with an adaptive modulation function. A requested band of the piece of traffic is compared with an allocatable band allocatable to a first path candidate that is included in the plurality of path candidates and that satisfies a degree of stability requested by the piece of traffic by a first modulation method. As a result of the comparison, when the requested band of the piece of traffic is larger than the allocatable band, a penalty cost due to transmission using a band usable by a second modulation method having a lower degree of stability is given to the first path candidate so that the first path candidate is less likely to be selected as compared with the other path candidates for selecting one path from among the plurality of path candidates.
