Decision Rules, Bayes' Rule and Ruogh Sets

  title={Decision Rules, Bayes' Rule and Ruogh Sets},
  author={Zdzislaw Pawlak},
This paper concerns a relationship between Bayes’ inference rule and decision rules from the rough set perspective. In statistical inference based on the Bayes’ rule it is assumed that some prior knowledge (prior probability) about some parameters without knowledge about the data is given first. Next the posterior probability is computed by employing the available data. The posterior probability is then used to verify the prior probability. In the rough set philosophy with every decision rule… CONTINUE READING
