FindClustersAuto {ADPclust} | R Documentation |
This is the subroutine that automatically finds cluster assignments from given f and delta by testing various parameter settings and find the one that maximizes the silhouette.
FindClustersAuto(distm, f, delta, ac = 1, nclust = 2:10, f.cut = c(0.1, 0.2, 0.3))
distm |
the distance matrix |
f |
vector of local distance f(x). See the help of adpclust() for details. |
delta |
vector of minimal distances to higher ground delta(x). See the help of adpclust() for details. |
ac |
type of auto selection. The valid options are 1 and 2. See the help of adpclust() for details. |
nclust |
number of clusters to test. Either a single integer or a vector of integers. |
f.cut |
number between (0, 1) or numeric vector of numbers between (0, 1). Data points whose f values are larger than f.cut with large delta values are selected as centers. The default is c(0.1, 0.2, 0.3). See the help of FindCentersAutoV() for more details. |
list of four elements:
clusters Cluster assignments. A vector of the same length as the number of observations.
centers: Indices of the clustering centers.
silhouette: Silhouette score from the final clustering result.
nclust: Number of clusters.
