Energy parameters reduction of bijective soft set based on the significance

摘要

Soft set theory is a newly emerging tool to deal with uncertain problems. Bijective soft set is a branch of the soft set. Energy parameter reduction is an important step in knowledge discovery of soft set theory. This paper presents a new parameters reduction method based on the significance of parameters. The new algorithm begins with the energy parameter significance, adopting iterative feature selection and get the reduction of the condition parameters finally .And the method is compared with the results of the other reduction methods to prove it's feasibility and effectiveness.
