Kmeans performance difference
...ring with apparently the exact same parameters behaves so differently between the two following examples : > cl1 <- kmeans(subset(pointsUXO15555, select = c(2:4)), 10) Takes about 2 seconds to deliver a result > cl1 <- clust(subset(pointsUXO15555, select = c(2:4)), k=10, method="kmeansHartigan") Dies after about 10 minutes and fills up RAM : *** running kmeansHartigan cluster algorithm... *** calculating validity measure... Erreur : impossible d'allouer un vecteur de taille 922.9 Mo De plus : Warning messages: 1: Reached total allocation of 1023Mb: see help(memory.size)...
