ml-model-constructors

Constructors for 'ml_model' Objects

Description

Functions for developers writing extensions for Spark ML. These functions are constructors for 'ml_model' objects that are returned when using the formula interface.

Usage

ml_supervised_pipeline(predictor, dataset, formula, features_col, label_col)

ml_clustering_pipeline(predictor, dataset, formula, features_col)

ml_construct_model_supervised(
  constructor,
  predictor,
  formula,
  dataset,
  features_col,
  label_col,
  ...
)

ml_construct_model_clustering(
  constructor,
  predictor,
  formula,
  dataset,
  features_col,
  ...
)

new_ml_model_prediction(
  pipeline_model,
  formula,
  dataset,
  label_col,
  features_col,
  ...,
  class = character()
)

new_ml_model(pipeline_model, formula, dataset, ..., class = character())

new_ml_model_classification(
  pipeline_model,
  formula,
  dataset,
  label_col,
  features_col,
  predicted_label_col,
  ...,
  class = character()
)

new_ml_model_regression(
  pipeline_model,
  formula,
  dataset,
  label_col,
  features_col,
  ...,
  class = character()
)

new_ml_model_clustering(
  pipeline_model,
  formula,
  dataset,
  features_col,
  ...,
  class = character()
)

Arguments

`predictor`	The pipeline stage corresponding to the ML algorithm.
`dataset`	The training dataset.
`formula`	The formula used for data preprocessing
`features_col`	Features column name, as a length-one character vector. The column should be single vector column of numeric values. Usually this column is output by `ft_r_formula`.
`label_col`	Label column name. The column should be a numeric column. Usually this column is output by `ft_r_formula`.
`constructor`	The constructor function for the 'ml_model'.
`pipeline_model`	The pipeline model object returned by 'ml_supervised_pipeline()'.
`class`	Name of the subclass.
