Spark ML -- One vs Rest

Perform regression or classification using one vs rest.

Usage
ml_one_vs_rest(x, classifier, response, features, ml.options = ml_options(),
  ...)
Arguments
x

An object coercable to a Spark DataFrame (typically, a tbl_spark).

classifier

The classifier model. These model objects can be obtained through the use of the only.model parameter supplied with ml_options.

response

The name of the response vector (as a length-one character vector), or a formula, giving a symbolic description of the model to be fitted. When response is a formula, it is used in preference to other parameters to set the response, features, and intercept parameters (if available). Currently, only simple linear combinations of existing parameters is supposed; e.g. response ~ feature1 + feature2 + .... The intercept term can be omitted by using - 1 in the model fit.

features

The name of features (terms) to use for the model fit.

ml.options

Optional arguments, used to affect the model generated. See ml_options for more details.

...

Optional arguments; currently unused.
