Outlier detection in a multiset-valued information system based on rough set theory and granular computing

Y Song, H Lin, Z Li - Information Sciences, 2024 - Elsevier
Outlier detection on data with missing information values is especially tricky because the
uncertainty caused by missing information values may contribute to an object being an …

Multiset topologies induced by multiset relations

KP Girish, SJ John - Information Sciences, 2012 - Elsevier
Multiset topology is a collection of multisets which satisfies the axioms of topology. In this
paper, multiset topologies are obtained using binary multiset relations. The relationship …

Mathematical properties of soft cardinality: Enhancing Jaccard, Dice and cosine similarity measures with element-wise distance

S Jimenez, FA Gonzalez, A Gelbukh - Information Sciences, 2016 - Elsevier
The soft cardinality function generalizes the concept of counting measure of the classic
cardinality of sets. This function provides an intuitive measure of the amount of elements in a …

Semi-supervised attribute reduction for partially labelled multiset-valued data via a prediction label strategy

Z Li, T Yang, J Li - Information Sciences, 2023 - Elsevier
The existence of a large amount of partially labelled data is due to the high cost of labelled
data. For this type of data, traditional rough set models cannot well represent the distribution …
