Improved D-S evidence theory for pipeline damage identification [PDF]

open access: yesJournal of Vibroengineering, 2015
Identification of the location of damages in pipeline is important and still needs to be improved due to the problems such as limited number of sensors that can be placed in the pipeline, uncertainty of the working environment. In this paper, a new approach is presented, which shows an improved diagnosis performance.

Feature Selection for Interval-Valued Data Based on D-S Evidence Theory

open access: yesIEEE Access, 2021
Feature selection is one basic and critical technology for data mining, especially in current “big data era”. Rough set theory (RST) is sensitive to noise in feature selection due to the strict condition of equivalence relation.
