WebSep 13, 2011 · By about 1980 phenetic approaches had been pushed aside by phylogenetic systematics, but Sneath and Sokal’s work is still regarded by mathematical clusterers as the most important founding work in their field. The most widely-used of Sneath’s methods is the UPGMA clustering method (independently also invented by F. J. Rohlf). WebLos trabajos de Sokal y Sneath , marcan el inicio de las técnicas de clusterización, que, poco a poco, han ido extendiendo sus aplicaciones a todos los ámbitos científicos.

WebThe percentage of improvement with respect to the best classical dissimilarity metric (Sokal-Sneath) is within the interval [0.7, 6]. In addition, the obtained new metric clearly outperforms the results of the Euclidean based p-persistence. Regarding redundancy, the proposed approach outperforms flooding and it is closed to Sokal-Sneth metric. Peter Henry Andrews Sneath FRS, MD (17 November 1923 – September 9, 2011) was a microbiologist who co-founded the field of numerical taxonomy, together with Robert R. Sokal. Sneath and Sokal wrote Principles of Numerical Taxonomy, revised in 1973 as Numerical Taxonomy. Sneath reviewed the state of numerical taxonomy in 1995 and wrote some autobiographical notes in 2010.
