Accelerator for multi-granularity attribute reduction

作者：

Highlights：

• The multi-granularity is introduced into attribute reduction.

• An acceleration strategy is proposed to speed up the process of finding multi-granularity reduct.

• Our approach can reduce the time consumption of finding reduct.
