h2o.tot_withinss: Get the total within cluster sum of squares.

In h2o: R Interface for the 'H2O' Scalable Machine Learning Platform

Get the total within cluster sum of squares.

Description

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".

Usage

h2o.tot_withinss(object, train = FALSE, valid = FALSE, xval = FALSE)

Arguments

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

Examples

## Not run:

fr <- h2o.importFile("https://h2o-public-test-data.s3.amazonaws.com/smalldata/iris/iris_train.csv")
predictors <- c("sepal_len", "sepal_wid", "petal_len", "petal_wid")
km <- h2o.kmeans(x = predictors, training_frame = fr, k = 3, nfolds = 3)
h2o.tot_withinss(km, train = TRUE)
