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.

Attribute-based transactions in service oriented computing
, 2014 We present a theory for the design and verification of distributed transactions in dynamically reconfigurable systems. Despite several formal approaches have been proposed to study distributed transactional behaviours, the inter-relations between failure

A Distributed Attribute Reduction Algorithm for High-Dimensional Data under the Spark Framework
International Journal of Computational Intelligence Systems, 2022 Attribute reduction is an important issue in rough set theory. However, the rough set theory-based attribute reduction algorithms need to be improved to deal with high-dimensional data.

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.

Genetic Programming for Attribute Construction in Data Mining [PDF]
, 2003 For a given data set, its set of attributes defines its data space representation. The quality of a data space representation is one of the most important factors influencing the performance of a data mining algorithm.

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
