Abstract
This signal analysis device provides information to assist determining the state of a time series signal. An identification unit (120) identifies events included in the time series signal, and a ranking generation unit (140) generates a ranking among multiple event types.
Claims8
A signal analysis device comprising:
- a memory storing instructions;
- and
- at least one processor configured to execute the instructions to perform:
- detecting events included in a time-series signal, each event having an event type;
- calculating an evaluation value for each event type of the detected events;
- and
- generating a ranking of a plurality of the event types of the detected events based on the evaluation value for each event type.

A signal analysis method performed by a computer and comprising:
- detecting events included in a time-series signal, each event having an event type;
- calculating an evaluation value for each event type of the detected events;
- and
- generating a ranking of a plurality of the event types of the detected events based on the evaluation value for each event type.
1 more element
A non-transitory recording medium storing a program for causing a computer to perform:
- detecting events included in a time-series signal, each event having an event type;
- calculating an evaluation value for each event type of the detected events;
- and
- generating a ranking of a plurality of the event types of the detected events based on the evaluation value for each event type.
