%description
Various clustering algorithms that produce a credal partition, i.e., a set
of Dempster-Shafer mass functions representing the membership of objects
to clusters. The mass functions quantify the cluster-membership
uncertainty of the objects. The algorithms are: Evidential c-Means,
Relational Evidential c-Means, Constrained Evidential c-Means, Evidential
Clustering, Constrained Evidential Clustering, Evidential
K-nearest-neighbor-based Clustering, Bootstrap Model-Based Evidential
Clustering, Belief Peak Evidential Clustering, Neural-Network-based
Evidential Clustering.
