One way to determine the quality of the clustering is to measure the expected self-similar nature of the points in a set of clusters. The silhouette value does just that and it is a measure of how similar a …
WebAug 22, 2024 · Abstract. Clustering homologous sequences based on their similarity is a problem that appears in many bioinformatics applications. The fact that sequences cluster is ultimately the result of their phylogenetic relationships. Despite this observation and the natural ways in which a tree can define clusters, most applications of sequence ...
