called interval-valued data. In this paper a fuzzy clustering method to analyse interval …

Trimmed fuzzy clustering for interval-valued data

P D'Urso, L De Giovanni, R Massari - Advances in Data Analysis and …, 2015 - Springer
In this paper, following a partitioning around medoids approach, a fuzzy clustering model for

[HTML][HTML] Fuzzy clustering of spatial interval-valued data

P D'Urso, L De Giovanni, L Federico, V Vitale - Spatial Statistics, 2023 - Elsevier
In this paper, two fuzzy clustering methods for spatial interval-valued data are proposed, ie

Fuzzy clustering of fuzzy data based on robust loss functions and ordered weighted averaging

P D'Urso, JM Leski - Fuzzy Sets and Systems, 2020 - Elsevier
In many real cases the data are not expressed in term of single values but are imprecise. In
all these cases, standard clustering methods for single-valued data are unable to properly …

Fuzzy clustering of interval-valued data with City-Block and Hausdorff distances

FAT de Carvalho, EC Simões - Neurocomputing, 2017 - Elsevier
Interval-valued data arises in situations where it is needed to manage either the uncertainty
related to measurements, or the variability inherent to a group rather than an individual. This …
