Usage
ml_multilayer_perceptron(x, response, features, layers, iter.max = 100, seed = sample(.Machine$integer.max, 1), ml.options = NULL, ...)
Arguments
x
An object coercable to a Spark DataFrame (typically, a
tbl_spark
).
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.
layers
A numeric vector describing the layers -- each element in the vector
gives the size of a layer. For example, c(4, 5, 2)
would imply three layers,
with an input (feature) layer of size 4, an intermediate layer of size 5, and an
output (class) layer of size 2.
iter.max
The maximum number of iterations to use.
seed
A random seed. Set this value if you need your results to be
reproducible across repeated calls.
ml.options
Optional arguments, used to affect the model generated. See
ml_options
for more details. ...
Optional arguments; currently unused.
