If "train", "valid", and "xval" parameters are FALSE (default), then the training tot_withinss value is returned. If more than one parameter is set to TRUE, then a named vector of tot_withinss' are returned, where the names are "train", "valid" or "xval".
h2o.tot_withinss(object, train = FALSE, valid = FALSE, xval = FALSE)
object | An H2OClusteringModel object. |
---|---|
train | Retrieve the training total within cluster sum of squares |
valid | Retrieve the validation total within cluster sum of squares |
xval | Retrieve the cross-validation total within cluster sum of squares |
