Non-commitment Entropy: A Noval Modality for Uncertainty Measurement
Pengyuan Wei, Kun She, Wei Pan · 2015
Three-way decision rule is the extension of traditional two-way decision. In the real environment, a decision maker is not easy to make choice between acceptance and rejection for the uncertainly or incomplete information. In this case, people used to choose three-way decision for the uncertain and high risky decision with extra but necessary cost. Meanwhile some general uncertainty measures are proposed by generalizing Shannon’s entropy. The theory of information entropy makes the uncertainty measures more accuracy in boundary of three-way decision. In this paper, we propose several types of non-commitment entropy by using the relation of the ‘third’ decision—non-commitment, and employ the proposed model to evaluate the significance of the attributes for classification as well.
