Remarks

The status of a character is set to Confused if the score satisfies the accept threshold but the confidence score does not satisfy the confidence threshold.

A character's confidence score is the difference between the score of the classification (the highest scoring training instance) and the score of the next-highest classification (the highest scoring training instance from a different class).

Note: Even if the confidence score satisfies the confidence threshhold, the character status may still be set to Confused if the classification validation check does not pass.
