RESEARCH ON IMPROVING SOME MEASUREMENTS IN CRUDE THEORETICAL OF INCOMPLETE DECISION TABLES

Abstract

Attribute reduction methods uses measurements by tolerance layers, such as the measurement of information quantity.  To solve the problem of reducing attributes directly on the incomplete decision tables and assessing changes in the value of certainty, consistency, support. These measures have difficulty in assessing the effectiveness (in terms of the ability to classify or support the law set) ...In this paper, the author improved some measurements to improve performance in the crude theoretical for incomplete decision tables and proved the validity of the proposed measurements.
