%description
The Self-Organizing Maps with Built-in Missing Data Imputation. Missing
values are imputed and regularly updated during the online Kohonen
algorithm. Our method can be used for data visualisation, clustering or
imputation of missing data. It is an extension of the online algorithm of
the 'kohonen' package. The method is described in the article
"Self-Organizing Maps for Exploration of Partially Observed Data and
Imputation of Missing Values" by S. Rejeb, C. Duveau, T. Rebafka (2022)
<arXiv:2202.07963>.
