Generalized objects in the system with dispersed knowledge

作者：

Highlights：

• Dispersed decision system is used.

• Definition of generalized objects that are suitable for quantitative data is given.

• Definition of generalized objects with accuracy for qualitative data is given.

• The use of generalized objects significantly reduces objects in local tables.

• For large number of attributes comparable accuracy are obtained for full objects.
