Abstract

By applying the test theory, an object can be placed into a subspace within the hyperspace of features, which in turn gives a probability of correct classification (predictive value or diagnosability). Once the predictive value reaches or exceeds the predetermined confidence limit after a finite number of observations (tests) of the features, no additional observation is necessary. A discriminant for a given feature is set from empirical values ("experiences"), an observation of a feature needs not be a precise measure. Instead, a comparison whether the feature is greater or lesser than the discriminant can be used. Information of tests will give clues to decide the sequence of the tests in a descending order of information to classify an object with the minimum number of observa-tions. These strategies reduce the time required for observations of features and computation, and shortens the execution of pattern recognition.
