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 … In statistics and data mining, affinity propagation (AP) is a clustering algorithm based on the concept of "message passing" between data points. Unlike clustering algorithms such as k-means or k-medoids, affinity propagation does not require the number of clusters to be determined or estimated before running the algorithm. Similar to k-medoids, affinity propagation finds "exemplars," members of the input set that are representative of clusters.
