The Relation between the Error Distribution and the Error Rate in Identification Experiments*
نویسنده
چکیده
The error dispersion is a perplexity related measure of the effective number of error categories used by listeners in an identification experiment. The error difference is calculated from the error dispersions of several confusion matrices and measures the difference between these confusion matrices. The error dispersion and the error difference are largely independent of the error rate. It is shown in this paper that correlations (and the absence thereof) between the error dispersion and the error rate that are found in identification experiments can be used to infer underlying regularities in the identification process. The use of these techniques is demonstrated with examples from the literature.

The feature map represented by the set of weight vectors of the basic SOM (Self-Organizing Map) provides a good approximation to the input space from which the sample vectors come. But the timedecreasing learning rate and neighborhood function of the basic SOM algorithm reduce its capability to adapt weights for a varied environment. In dealing with non-stationary input distributions and changi...

The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a new method is introduced for determining the relationship between spectrophotometric error and colorimetric inaccuracy. The error propagation in colorimetric parameter calculation is evaluated using a linear relation between variance of reflectance spectra and CIE tristimulus values. This linear formula ca...
