Information fusion and numerical characterization of a multi-source information system

作者:

Highlights:

• In order to take fully advantage of evidence theory and integrate multi-granulation structures, we propose the novel definitions of multi-source rough approximations and corresponding multi-granulation rough approximations, probability distribution and basic probability assignment, then construct the connection between rough approximations and evidence theory.

• The results in (1) are extended to multi-source covering information system.

• Two Shannon’s fusion algorithms based on equivalence relations and coverings, involved in the significance degree of condition attributes set with respect to a sample, conditional probability and information entropy, are presented to measure the classification uncertainty degree of a decision class or a decision partition in a multi-source information system, respectively.

• By combining the significance degree and conditional probability, defined in this paper, we design a multi-granulation probabilistic rough set and considered the relationship with Multi-granulation rough set.
