WebJul 6, 2011 · 1 INTRODUCTION. Affinity propagation (AP) is a relatively new clustering algorithm that has been introduced by Frey and Dueck (2007).AP clustering determines a so-called exemplar for each cluster, that is, a sample that is most representative for this cluster. Like agglomerative clustering, AP has the advantage that it works for any … WebJan 24, 2024 · This is a model-based clustering algorithm that returns a hierarchy of classes, similar to hierarchical clustering, but also similar to finite mixture models.
