- W3022920912 abstract "This work presents a systematic study of objective evaluations of abstaining classifications using information-theoretic measures (ITMs). First, we define objective measures as the ones which do not depend on any free parameter. According to this definition, technical simplicity for examining objectivity or subjectivity is directly provided for classification evaluations. Second, we propose 24 normalized ITMs for investigation, which are derived from either mutual information, divergence, or cross-entropy. Contrary to conventional performance measures that apply empirical formulas based on users intuitions or preferences, the ITMs are theoretically more general for realizing objective evaluations of classifications. They are able to distinguish and in binary classifications without the need to inputting data of cost terms. Third, to better understand and select the ITMs, we suggest three desirable features for classification assessment measures, which appear more crucial and appealing from the viewpoint of classification applications. Using these features as we can reveal the advantages and limitations of ITMs from a higher level of evaluation knowledge. Numerical examples are given to demonstrate our claims and compare the differences among the proposed measures. The best measure is selected in terms of the meta-measures, and its specific properties regarding error types and reject types are analytically derived." @default.
