State detecting device, state detecting method, and non-transitory computer-readable medium
First Claim
1. A state detecting device, comprising:
- a characteristic quantity detector for detecting information regarding a monitored subject as characteristic quantities;
a sorter for sorting multiple classes defining the activity level of a monitored subject into a first group and a second group based on a code table, each group having at least one or more classes, and associating the sorted multiple classes with the characteristic quantities detected by the characteristic quantity detector;
multiple identification devices for receiving the characteristic quantities associated by the sorter as input values, identifying whether a state of the monitored subject belongs to the first group or the second group based on the input values, and outputting information including the identification results and credibility level as output values;
a loss value calculator for calculating loss values of the each class based on the each output values output from the multiple identification devices and the code table; and
a class detector for detecting a class to which the state of the monitored subject belongs among the multiple classes based on the loss values of the each class;
wherein the code table is determined by the number of identification devices and the number of classes.

Abstract
Disclosed is a state detecting device that detects characteristic quantities regarding the driver that are represented by biological information such as the eyelid opening degree and frequency of heartbeat of the driver, identifies the group to which the state of the driver belongs between a Group 1 and a Group 2 into which multiple classes defined using the activity level of the driver as an indicator are sorted based on the detected characteristic quantities, outputs information including the identification results as output values, and detects the class to which the current state of the driver belongs based on loss values calculated from the output values. From the detected class, to what degree the activity level of the driver is impaired can be detected along with the level.
