Reduct-based ranking of attributes
Procedia Computer Science, 2020 Abstract The paper is dedicated to the area of feature selection, in particular a notion of attribute rankings that allow to estimate importance of variables. In the research presented for ranking construction a new weighting factor was defined, based on relative reducts.

Stream Convolution for Attribute Reduction of Concept Lattices
Mathematics, 2023 Attribute reduction is a crucial research area within concept lattices. However, the existing works are mostly limited to either increment or decrement algorithms, rather than considering both.

Service attribute importance and strategic planning: An empirical study [PDF]
, 2008 There is growing evidence that attribute importance is a function of attribute performance. Several studies reported that service quality attributes fall into three categories: basic, performance, and excitement.

Optimal Granularity Selection and Attribute Reduction in Meso-granularity Space [PDF]
, 2023 The conventional formal concept analysis adopts a meso-granularity formal context to meet the requirements of cross-layer granulation of data.However,it does not effectively combine the search for optimal granularity with attribute reduction,nor does it ...

Information Entropy-Based Attribute Reduction for Incomplete Set-Valued Data
IEEE Access, 2022 This paper investigates attribute reduction for incomplete set-valued data based on information entropy. The similarity degree between information values on a conditional attribute of an incomplete set-valued decision information system (ISVDIS) is first

Interpretation and reduction of attribute grammars [PDF]
Acta Informatica, 1983 An attribute grammar (AG) is in reduced form if in all its derivation trees every attribute contributes to the translation. We prove that, eventhough AG are generally not in reduced form, they can be reduced, i.e., put into reduced form, without modifying their translations. This is shown first for noncircular AG and then for arbitrary AG.
