Model-based clustering of Gaussian copulas for mixed data
Matthieu Marbac, Christophe Biernacki, Vincent Vandewalle
Clustering task of mixed data is a challenging problem. In a probabilistic framework, the main difficulty is due to a shortage of conventional distributions for such data. In this…
Finite mixture model of conditional dependencies modes to cluster categorical data
Matthieu Marbac, Christophe Biernacki, Vincent Vandewalle
We propose a parsimonious extension of the classical latent class model to cluster categorical data by relaxing the class conditional independence assumption. Under this new mixtur…
Model-based clustering for conditionally correlated categorical data
Matthieu Marbac, Christophe Biernacki, Vincent Vandewalle
An extension of the latent class model is presented for clustering categorical data by relaxing the classical "class conditional independence assumption" of variables. This model c…
