ml_naive_bayes
Spark ML -- Naive-Bayes
Perform regression or classification using naive bayes.
Usage
ml_naive_bayes(x, response, features, lambda = 0, ml.options = ml_options(),
...)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
responseis a formula, it is used in preference to other parameters to set theresponse,features, andinterceptparameters (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- 1in the model fit.- features
The name of features (terms) to use for the model fit.
- lambda
The (Laplace) smoothing parameter. Defaults to zero.
- ml.options
Optional arguments, used to affect the model generated. See
ml_optionsfor more details.- ...
Optional arguments. The
dataargument can be used to specify the data to be used whenxis a formula; this allows calls of the formml_linear_regression(y ~ x, data = tbl), and is especially useful in conjunction withdo.
