Abstract
Humans are adept at providing accurate statements of confidence in their perceptual identification and recall memory responses. In spite of this, mechanical pattern-recognition systems and other artificial intelligence devices seldom express response certainty. The purpose of this paper is to show how useful confidence ratings can be in integrating the results of a variety of pattern-recognition systems to produce a single, optimal decision concerning the target to be recognized. We outline several ways neural network pattern-recognition systems could be modified to issue confidence ratings with each classification response. In sketching a mechanical system of confidence ratings we find we have also provided a preliminary framework for understanding human confidence judgments and human metacognition.
