TimeSeriesTransformations
Transformations allowed on the dataset. Supported transformations are
Filling
and Aggregation
. Filling
specifies how to
add values to missing values in the dataset. Aggregation
defines how to
aggregate data that does not align with forecast frequency.
Contents
 Aggregation

A key value pair defining the aggregation method for a column, where the key is the column name and the value is the aggregation method.
The supported aggregation methods are
sum
(default),avg
,first
,min
,max
.Note
Aggregation is only supported for the target column.
Type: String to string map
Map Entries: Maximum number of 50 items.
Key Length Constraints: Minimum length of 1. Maximum length of 256.
Valid Values:
sum  avg  first  min  max
Required: No
 Filling

A key value pair defining the filling method for a column, where the key is the column name and the value is an object which defines the filling logic. You can specify multiple filling methods for a single column.
The supported filling methods and their corresponding options are:

frontfill
:none
(Supported only for target column) 
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 the chosen filling method value (for example
"backfill" : "value"
), and define the filling value in an additional parameter prefixed with "_value". For example, to setbackfill
to a value of2
, you must include two parameters:"backfill": "value"
and"backfill_value":"2"
