Abstract: A first information processing apparatus (2000) determines an alternative representation (20) of an event sequence represented by a plurality of event histories (12), by use of dictionary data (30). The first information processing apparatus (2000) outputs information including the determined alternative representation (20). The dictionary data (30) indicate an event sequence and an alternative representation (20) relating to the event sequence in association with each other.

Abstract: Based on a normal model, it is detected whether or not an event signal of a computer system is anomalous. In parallel with the normal-model-based anomaly detection, it is detected based on a rule whether or not the event signal is anomalous. Then, a final anomaly detection result is generated by performing comprehensive determination based on detection results of the normal-model-based anomaly detection and the rule-based anomaly detection.

Abstract: 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.

Abstract: Comfortability can be visually displayed for a user in real time while power consumption is controlled. A display device communicates to/from a power control device for controlling power of a power consumption system including a plurality of apparatus. An input unit specifies a desired set value for each of the plurality of apparatus or a power consumption system including the plurality of apparatus. A display unit displays a display content corresponding to a degree of divergence in real time when an amount of upper limit power for the entire power consumption system including the plurality of apparatus is set, the degree of divergence being calculated based on a comparison between an actual set value for the plurality of apparatus having an amount of power being subjected to demand control based on an evaluation function set for the plurality of apparatus and the desired set value specified through the input unit.
