The Error-reject Tradeoff
We investigate the error versus reject tradeo for classi ers. Our analysis is motivated by the remarkable similarity in error-reject tradeo curves for widely di ering algorithms classifying handwritten characters. We present the data in a new scaled version that makes this universal character particularly evident. Based on Chow's theory of the error-reject tradeo and its underlying Bayesian ana...
متن کاملOn Functional Relation between Recognition Error and Class-Selective Reject
This report reviews various optimum decision rules for pattern recognition, namely, Bayes rule, Chow's rule (optimum error-reject tradeo ), and a recently proposed class-selective rejection rule. The latter provides an optimum tradeo between the error rate and the average number of (selected) classes. A new general relation between the error rate and the average number of classes is presented. ...
متن کاملOptimum Reject Options for Prototype-based Classification
We analyse optimum reject strategies for prototype-based classifiers and real-valued rejection measures, using the distance of a data point to the closest prototype or probabilistic counterparts. We compare reject schemes with global thresholds, and local thresholds for the Voronoi cells of the classifier. For the latter, we develop a polynomial-time algorithm to compute optimum thresholds base...
متن کاملOn the Error-Reject Trade-Off in Biometric Verification Systems
In this work, we address the problem of performance evaluation in biometric verification systems. By formulating the optimum Bayesian decision criterion for a verification system and by assuming the data distributions to be multinormals, we derive two statistical expressions for calculating theoretically the false acceptance and false rejection rates. Generally, the adoption of a Bayesian param...
متن کاملError-tradeoff and error-disturbance relations for incompatible quantum measurements.
Heisenberg's uncertainty principle is one of the main tenets of quantum theory. Nevertheless, and despite its fundamental importance for our understanding of quantum foundations, there has been some confusion in its interpretation: Although Heisenberg's first argument was that the measurement of one observable on a quantum state necessarily disturbs another incompatible observable, standard unc...
