On the f-divergence for set-valued measures and non-additive set-valued measures

  • 摘要: 散度作为信息之间的一种度量,在分类问题中因表示信息之间的差异程度而得到广泛应用. 集值测度和非可加集值测度作为测度的推广,定义和讨论了集值测度和非可加集值测度的f-散度,H-散度和δ-散度,并利用集值的运算和偏序关系,证明了H-散度和δ-散度满足三角不等式性质和对称性,同时给出了集值测度和非可加集值测度Radon-Nikodym 导数存在的充分必要条件. 最后给出了算例.

     

    Abstract: Divergence as a degree of the difference between two data is widely used in the classification problems. In this paper, f-divergence, H-divergence and δ-divergence of the set-valued measures and non-additive set-valued measures are defined and discussed respectively. It is proved that H-divergence and δ-divergence satisfy the triangle inequality and symmetry by means of the set operations and partial ordering relations. Meanwhile, the necessary and sufficient conditions of Radon-Nikodym derivatives of the set-valued measures and non-additive set-valued measures are investigated respectively. Finally, some examples are given to illustrate the effectiveness of the definitions and results proposed in the article.
