ml_one_vs_rest
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 withml_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 theresponse
,features
, andintercept
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. The
data
argument can be used to specify the data to be used whenx
is a formula; this allows calls of the formml_linear_regression(y ~ x, data = tbl)
, and is especially useful in conjunction withdo
.
