FeaturizationMethod
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"}
}
Contents
- FeaturizationMethodName
-
The name of the method. The "filling" method is the only supported method.
Type: String
Valid Values:
filling
Required: Yes
- FeaturizationMethodParameters
-
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

,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"
