Overview

Note:

When making an API call, you may pass FeaturizationMethod data as a hash:

{
  featurization_method_name: "filling", # required, accepts filling
  featurization_method_parameters: {
    "ParameterKey" => "ParameterValue",
  },
}

Provides information about the method that featurizes (transforms) a dataset field. The method is part of the FeaturizationPipeline of the Featurization object.

The following is an example of how you specify a FeaturizationMethod object.

\{

"FeaturizationMethodName": "filling",

"FeaturizationMethodParameters": \{"aggregation": "sum", "middlefill": "zero", "backfill": "zero"\}

\}

Instance Attribute Details

#featurization_method_nameString

The name of the method. The "filling" method is the only supported method.

Returns:

The method parameters (key-value pairs), which are a map of override parameters. Specify these parameters to override the default values. Related Time Series attributes do not accept aggregation parameters.

The following list shows the parameters and their valid values for the "filling" featurization method for a Target Time Series dataset. Bold signifies the default value.

  • aggregation: sum, avg, first, min, max

  • frontfill: none

  • middlefill: zero, nan (not a number), value, median, mean, min, max

  • backfill: zero, nan, value, median, mean, min, max

The following list shows the parameters and their valid values for a Related Time Series featurization method (there are no defaults):

  • middlefill: zero, value, median, mean, min, max

  • backfill: zero, value, median, mean, min, max

  • futurefill: zero, value, median, mean, min, max

To set a filling method to a specific value, set the fill parameter to value and define the value in a corresponding _value parameter. For example, to set backfilling to a value of 2, include the following: "backfill": "value" and "backfill_value":"2".

Returns:

  • (Hash<String,String>)
