Managing variables

Recipes are JSON-structured scripts that contains the following three sections in the given order:

  • Groups
  • Assignments
  • Outputs

An empty recipe instructing Amazon ML to take all the dataset variables into account for model training will be as follows:

{    "groups" : {},    "assignments" : { },    "outputs":["ALL_INPUTS"]}

The recipe does not transform the data in any way.
