h2o (version 3.2.0.3)

h2o.r2: Retrieve the R2 value

Description

Retrieves the R2 value from an H2O model. If "train", "valid", and "xval" parameters are FALSE (default), then the training R2 value is returned. If more than one parameter is set to TRUE, then a named vector of R2s are returned, where the names are "train", "valid" or "xval".

Usage

h2o.r2(object, train = FALSE, valid = FALSE, xval = FALSE, ...)

Arguments

object

An H2OModel object.

train

Retrieve the training R2

valid

Retrieve the validation R2

xval

Retrieve the cross-validation R2

...

extra arguments to be passed if `object` is of type H2OModel (e.g. train=TRUE)

Examples

library(h2o)

h <- h2o.init()
fr <- as.h2o(iris)

m <- h2o.deeplearning(x=2:5,y=1,training_frame=fr)

h2o.r2(m)
