%description
Functional clustering aims to group curves exhibiting similar temporal
behaviour and to obtain representative curves summarising the typical
dynamics within each cluster. A key challenge in this setting is class
imbalance, where some clusters contain substantially more curves than
others, which can adversely affect clustering performance. While class
imbalance has been extensively studied in supervised classification, it
has received comparatively little attention in unsupervised clustering.
This package implements functional iterative hierarchical clustering
('funIHC'), an adaptation of the iterative hierarchical clustering method
originally developed for multivariate data, to the functional data
setting. For further details, please see Higgins and Carey (2024)
<doi:10.1007/s11634-024-00611-8>.
