Interval-valued Decision-theoretic Rough Sets
Huaxiong Li · 2012
By considering the multiple-valued character in practical decision procedure,the interval-valued loss functions were induced to decision-theoretic rough set theory(DTRS) based on the Bayesian decision theory.With respect to the minimum Bayesian expected risk,a model of interval-valued decision-theoretic rough set theory was built.The corresponding propositions and criteria of interval-valued decision-theoretic rough set theory were also analyzed.An example of oil investment was given to illuminate the proposed model in applications.
