explode

Explode(features)

Bases: Transform

Explodes a Dataframe to long format by exploding the given features.

Parameters:

Name	Type	Description	Default
features	list[str]	List of features to explode.	required

The below example shows the usage of a Explode transform in an experiment.yaml file. Assuming the loaded data is represented by the table:

time	feature_a	feature_b	constant
[0, 1]	[2, 1]	[9, 3]	1
[0, 2]	[3, 4]	[8, 4]	2

This transform can be used to explode the columns time, feature_a, and feature_b.

The resulting Dataframe after the transform is:

time	feature_a	feature_b	constant
0	2	9	1
1	1	3	1
0	3	8	2
2	4	4	2
